Numerical Investigation and Optimization of Cooling Flow Field Design for Proton Exchange Membrane Fuel Cell

Energies, 2022
High temperatures and non-uniform temperatures both have a negative bearing on the performance of proton exchange membrane fuel cells. The temperature of proton exchange membrane fuel cells can be lowered by reasonably distributed cooling channels.
