Fuel cell with protruded gas diffusion layer |
摘要 |
An assembling operation of a fuel cell is effectively simplified. With the simple and economical structure, the desired sealing function is achieved. The fuel cell includes a membrane electrode assembly and first and second metal separators sandwiching the membrane electrode assembly. Connection channels are provided on the first metal separator. The connection channels connect the oxygen-containing gas supply passage and the oxygen-containing gas discharge passage to the oxygen-containing gas flow field. The membrane electrode assembly has first overlapping portions overlapped on the connection channels for sealing the connection channels. The first overlapping portions comprise, in effect, a gas diffusion layer.
