<P>PROBLEM TO BE SOLVED: To provide a fuel cell capable of restraining degradation of power generation performance. <P>SOLUTION: The fuel cell (100) is provided with a power generating part (24) including an anode, electrolyte, and a cathode, porous body flow channels (50, 60) fitted at least at either an anode side or a cathode side of the power generating part, and a separator (10) fitted at the porous body flow channels at an opposite side of the power generating part. The porous body flow channel comprises a high-porosity part (51, 61) with a porosity higher than an average porosity of the porous body flow channel and a low-porosity part with a porosity lower than the average, the high-porosity part communicated with a gas exhaust side manifold (41b, 42b) through the low-porosity part. <P>COPYRIGHT: (C)2008,JPO&INPIT |
