Fuel cell using variable porosity gas diffusion material and method of operation
A fuel cell ( 100 ) includes a membrane electrode assembly ( 110 ) located together with a layer of variable porosity porous gas diffusion material ( 150 ). The variable porosity gas diffusion material layer ( 150 ) operates to selectively limit the amount of reactants reaching localized areas of th...

| Zusammenfassung: | A fuel cell ( 100 ) includes a membrane electrode assembly ( 110 ) located together with a layer of variable porosity porous gas diffusion material ( 150 ). The variable porosity gas diffusion material layer ( 150 ) operates to selectively limit the amount of reactants reaching localized areas of the membrane electrode assembly ( 110 ) in order to reduce hot spots. |
