Abstract:
A gas diffusion layer for fuel cell of the present invention is structured with a porous member mainly comprised of conductive particles such as acetylene black, graphite and a polymer resin such as PTFE. This makes it possible to achieve both an improvement in power generation performance of the fuel cell and a reduction in costs.
