1. Thermal Management of Fuel Cells Comprehensive Report with Schematics and Case Studies

2. Heat Generation in Fuel Cells Energy balance: Q = ΔH - ΔG Heat sources: activation, ohmic, and concentration losses. 40–60% of input energy is released as heat.

3. Cooling Methods in Fuel Cells Passive Cooling: conduction, radiation, phase-change materials. Active Cooling: air, liquid, heat pipes, refrigeration systems. Hybrid Systems: combine cooling with waste heat recovery.

4. Flow Field Designs Coolant flow field design (parallel, serpentine, pin-type). Temperature uniformity is critical (<10 °C gradients). Stack scaling increases cooling complexity. [Diagram Placeholder: Flow field designs]

5. Case Study: PEMFC in Automobiles Toyota Mirai uses 114 kW PEMFC stack. Liquid cooling with heat exchangers. Coolant temperature: 60–80 °C. Heat rejection ~100 kW at full load. [Diagram Placeholder: Toyota Mirai cooling system schematic]

6. Case Study: SOFC in Stationary Power Bloom Energy SOFC operates at ~800 °C. Waste heat recovery for combined heating. 50% electrical + 30–35% thermal efficiency. [Diagram Placeholder: SOFC CHP layout]
