The hydrogen polymer electrolyte membrane (PEM) fuel cellnprovides enormous potential for a clean energy infrastructure. Energynextracted from intermittent renewable energy sources, such as solarnand wind, can potentially be stored as hydrogen and used with PEMnfuel cells to produce on-demand ...
in the phosphoric acid fuel cell (PAFC) literature. This is because the best performing PAFC fuel cells involve supporting the catalyst on carbon-fiber paper that is made hydrophobic in order to retain the liquid electrolyte between the two electrodes. Note that the PEFC diffusion media ...
Wenmiao Chen Zhi Liu Abstract Micro porous layer (MPL)is a carbon layer (∼15 μm) that coated on the gas diffusion layer (GDL)to enhance the electrical conduction and membrane hydration of proton exchange membrane fuel cell (PEMFC).However, the liquid transport behavior from MPL to GDL ...
Gas diffusion layers (GDLs) have been widely used in fuel cells and electrolyzers due to their important role in facilitating the transport of reactants and products. The thermal conductivity of GDLs is a critical property that affects the heat dissipation and temperature distribution within the ...

One of the most significant obstacles for passive direct methanol fuel cells is the methanol crossover, since methanol diffuses through the membrane generating heat but no power. This can be reduced if the cell operates with low methanol concentrations. However, this significantly reduces the energy...
Measuring the amount of water in GDL is very important, because it is very closely linked to the performance of fuel cell. Flooding can be occurred at the beginning of the start up with high current densities. In order to know the amount of water in GDL, the dew point temperature of the...
