Polymer electrolyte membrane fuel cell comprises membrane-electrode arrangement having gas diffusion electrode with hydrophilic nano-porous catalytic layer and first hydrophobic nano-porous gas diffusion layer

摘要

A polymer electrolyte membrane fuel cell comprises a membrane-electrode arrangement having a gas diffusion electrode with a hydrophilic nano-porous catalytic layer and a first hydrophobic nano-porous gas diffusion layer. The catalytic layer has a first flat side forming a boundary with the first gas diffusion layer and a second flat side forming a boundary with the polymer electrolyte membrane.
