Abstract
A fuel cell comprises a gas separator having a dense layer, with porous portions disposed on both faces of the dense layer. The fuel cell, therefore, can store excess electrolyte, and absorb volume changes in the electrolyte without accompanying 'flooding'. Further, the fuel cell can reduce the thickness of a unit cell, and improve the space factor to output of the fuel cell.
