Document Type and Number:
Japanese Patent JP2011096385
Kind Code:
A
Abstract:
To prevent flooding and plugging with holding cell resistance and contact resistance between a gas diffusion layer and a film electrode conjunction low.
In a gas diffusion layer for a cathode for a solid polymer fuel cell having a structure in which a film electrode conjunction comprising a gas diffusion layer for an anode and a gas diffusion layer for a cathode is sandwiched by a pair of separators, a gas diffusion layer 4 for a cathode has a through-hole 11 in a surface on its side of contacting a separator 9, and does not have any through-holes in a surface on a side opposite to the side of contacting the separator.
