Patent ID: 7709130

Claim:
A fuel cell comprising: a membrane electrode assembly including an anode, a cathode opposed to the anode, and an electrolyte membrane interposed between the anode and the cathode; a lyophobic porous body in contact with the anode; and an anode passage plate in contact with the lyophobic porous body, the anode passage plate including a gas collection passage and a fuel supplying passage, the gas collection passage collects a gas generated in the anode via the lyophobic porous body, the fuel supplying passage supplies a fuel to the anode via the lyophobic porous body, wherein the fuel supplying passage further includes a plurality of first passages in contact with the lyophobic porous body; and a plurality of second passages respectively connected to an upstream side of the first passages, and fluid diffusion resistances of the second passages are larger than fluid diffusion resistances of the first passages.
