A fuel cell vehicle (FCV) uses a hydrogen fuel cell to generate electricity, which powers an electric motor for propulsion, emitting only water vapor as a byproduct.
Hydrogen in fuel cell vehicles (FCVs) serves as the primary fuel that powers the vehicle. In a fuel cell, hydrogen reacts with oxygen from the air in an electrochemical process, producing electricity, water vapor, and heat. This electricity is then used to power the electric motor that drives the vehicle. The use of hydrogen in fuel cells offers a clean energy alternative, as the only emission from this process is water, making it an environmentally friendly option compared to traditional fossil fuels.
Fuel cells are known for their high efficiency, low emissions, and quiet operation, making them attractive for a wide range of applications, including transportation (such as hydrogen-powered vehicles), stationary power generation, and portable electronics.

INTRODUCTION Definition of fuel cells. A fuel cell is a device that converts the chemical energy from a fuel, typically hydrogen, into electricity through an electrochemical reaction with an oxidizing agent, typically oxygen or air. This process involves the conversion of fuel and oxidant into water, heat, and electricity, with no combustion occurring. Fuel cells operate based on the principle of electrochemical reactions occurring at electrodes, where fuel is oxidized at the anode and oxidant is reduced at the cathode, while ions transfer through an electrolyte. The electricity generated by fuel cells can be used to power various devices, from small electronics to vehicles, with high efficiency and low emissions. 20-05-2024 2
BASIC WORKING PRINCIPLES. A fuel cell is a galvanic cell in which the chemical energy of a fuel is converted directly into electrical energy by means of electrochemical processes. A fuel cell consists of an anode and a cathode, similar to a battery. The fuel supplied to the cell is hydrogen and oxygen. The concept of fuel cell is the opposite of electrolysis of water, where hydrogen and oxygen are combined to form electricity and water. 20-05-2024 3

TYPES OF FUEL CELLS Different Types of Fuel Cells include: 20-05-2024 5 03 Phosphoric Acid (PAFC 05 Solid Oxide (SOFC) 04 Alkaline (AFC) 06 Molten Carbonate (MCFC) 01 Direct Methanol (DMFC) 02 Polymer Electrolyte Membrane (PEMFC)
operates at relatively low temperatures (typically below 100°C) directly converts methanol fuel into electricity through an electrochemical reaction. Methanol is supplied to the anode, where it undergoes oxidation, releasing protons and electrons. At the cathode, oxygen (typically from air) combines with the protons and electrons to produce water as a byproduct. DMFCs are particularly suitable for portable and small-scale applications due to their high energy density and ease of fuel storage. 20-05-2024 6 Direct Methanol Fuel Cell (DMFC):
Proton Exchange Membrane Fuel Cell (PEMFC): uses a polymer electrolyte membrane (PEM) as the electrolyte. Hydrogen is supplied to the anode where it is oxidized, releasing protons and electrons. The protons migrate through the PEM to the cathode, while the electrons flow through an external circuit, generating electricity. At the cathode, oxygen (from air) combines with the protons and electrons to produce water as a byproduct. 20-05-2024 7
SOLID OXIDE FUEL CELL (SOFC): operates at high temperatures (typically between 500°C and 1000°C) and uses a solid ceramic electrolyte It can directly convert various fuels, including hydrogen, natural gas, and methane, into electricity through an electrochemical reaction. At the anode, fuel is oxidized, releasing electrons. oxygen ions migrate through the electrolyte to the cathode. At the cathode, oxygen combines with the electrons and any remaining fuel to produce water and/or carbon dioxide. 20-05-2024 8
MOLTEN CARBONATE FUEL CELL (MCFC): operates at high temperatures (typically between 600°C and 700°C) and uses a molten carbonate electrolyte, typically a mixture of lithium carbonate and potassium carbonate. Hydrogen and carbon dioxide are supplied to the anode, where hydrogen is oxidized, releasing electrons. carbonate ions migrate through the electrolyte to the cathode. At the cathode, oxygen combines with the electrons and carbonate ions to produce water, carbon dioxide, and heat. 20-05-2024 9
PHOSPHORIC ACID FUEL CELL (PAFC): operates at relatively moderate temperatures (typically between 150°C and 220°C) and uses phosphoric acid as the electrolyte, typically immobilized in a porous matrix. Hydrogen is supplied to the anode, where it is oxidized, releasing electrons. protons migrate through the electrolyte to the cathode. At the cathode, oxygen combines with the protons and electrons to produce water. 20-05-2024 10
ALKALINE FUEL CELL (AFC): operates at relatively low temperatures (typically below 100°C) and uses an alkaline electrolyte, typically potassium hydroxide (KOH) solution. Hydrogen is supplied to the anode, where it is oxidized, releasing electrons. The electrons flow through an external circuit, generating electricity, while hydroxide ions migrate through the electrolyte to the cathode At the cathode, oxygen combines with the hydroxide ions and electrons to produce water . 20-05-2024 11
HISTORICAL BACKGROUND AND DEVELOPMENT. The first fuel cells were invented by Sir William Grove in 1838. The first commercial use of fuel cells came almost a century later following the invention of the hydrogen–oxygen fuel cell by Francis Thomas Bacon in 1932. The alkaline fuel cell, also known as the Bacon fuel cell after its inventor, has been used in NASA space programs since the mid-1960s to generate power for satellites and space capsules. 20-05-2024 13 Sketch of Sir William Grove 's 1839 fuel cell
Cont. The first references to hydrogen fuel cells appeared in 1838. In a letter dated October 1838 but published in the December 1838 edition of The London and Edinburgh Philosophical Magazine and Journal of Science, Welsh physicist and barrister Sir William Grove wrote about the development of his first crude fuel cells. He used a combination of sheet iron, copper, and porcelain plates, and a solution of sulphate of copper and dilute acid. Grove later sketched his design, in 1842, in the same journal. The fuel cell he made used similar materials to today's phosphoric acid fuel cell. 20-05-2024 14 Sir William Grove
FUEL CELL ELECTRIC VEHICLES (FCEVS) Fuel cell electric vehicles (FCEVs) are similar in operation to BEVs except for the source of energy. Hydrogen fuel and the fuel cell replace the battery. The process of conversion is taken place by taking compressed hydrogen from the vehicle-mounted tank and mixing it with the atmospheric air that produces DC electricity to drive the electric motor and the water is produced as a by-product which is exhausted through the tailpipe. The FCEV is environmentally friendly because no carbon is involved in the fuel and hence no carbon dioxide, carbon monoxide, or hydrocarbons are emitted. In addition, there is no combustion is involved in the conversion process, and no high temperatures are involved. A schematic diagram of a FCEV is shown in Fig 20-05-2024 15
Differences between traditional Internal Combustion Engine (ICE) vehicles and Battery Electric Vehicles (BEVs): Efficiency : ICE vehicles have a 30% efficiency, while BEVs have an 80% efficiency. Emissions : ICE vehicles emit greenhouse gases, while BEVs have no tailpipe emissions. Charging time : ICE vehicles have a short refilling time of less than 5 minutes, while BEVs have a long charging time of 0.5 to 8 hours. Range : ICE vehicles can travel more than 600 km per fill, while BEVs can travel less than 250 km per charge. Energy density : BEVs have lower energy density batteries, while ICEs have fuels with high energy density. Torque delivery : BEVs deliver maximum torque instantaneously from zero RPM, while ICEs require complex gear systems to handle power and torque across various speeds. Maintenance : EVs may require less frequent ongoing maintenance and may have lower routine maintenance costs than ICE vehicles. Driving experience : EVs offer a green alternative with lower emissions, lower operating costs and a quieter driving experience. Infrastructure : ICE engines offer a long-established infrastructure. 20-05-2024 16
