    摘要： A fuel cell has a plurality of unit fuel cells and a gas manifold configured to path through the plurality of the unit fuel cells. Each of the plurality of unit fuel cells has an electrode and a separator. The separator includes in its interior a plurality of gas channels configured to communicate the gas manifold and a gas passage existing on a surface of the electrode. These gas channels include at least one gas through hole configured to open on a surface of the separator facing the electrode. The gas through holes provided on the plurality of gas channels include a first through hole group provided at a short distance from the gas manifold, and a second through hole group provided at a large distance from the gas manifold.

    摘要： A fuel cell includes a porous element, a first electrode, and a separator. The porous element is an element as a channel through which a reaction gas passes into the interior, the porous element having a first surface and a second surface. The first electrode is disposed on the first surface side of the porous element. The separator in contact with the second surface of the porous element is includes a first plate and a second plate, the first plate having a contact part in contact with the second surface, the second plate facing the first plate.

    摘要： A porous member is proposed which can be used as a gas diffusion electrode/separator of a proton exchange membrane fuel cell, is inexpensive and has superior long-term reliability, has low voltage loss when used as an electrode, and makes it possible to improve the power generating performance of the fuel cell and stabilize the power generating performance for a long time. A metallic porous body having a three-dimensional network structure and having an average pore diameter of 50 μm-1 mm and a porosity of not less than 80% is joined to a metal substrate such as metal foil by solid phase diffusion treatment to form an integral porous member.
