Patent ID: 8741500

Claim:
A fuel cell stack, comprising: a fuel cell layer constituted of two or more unit cells and having a first gap region provided between adjacent unit cells in the fuel cell layer; a spacer layer constituted of two or more spacers and having a second gap region provided between adjacent spacers in the spacer layer, the spacer layer being stacked on the fuel cell layer; and a current collection unit, each said unit cell including an anode catalyst layer, an electrolyte membrane, a cathode catalyst layer, and a fuel supply unit for supplying a fuel to said anode catalyst layer, the first gap region and the second gap region are a space penetrating the fuel cell layer and the spacer layer respectively in a direction of layer thickness thereof and constituting an oxidizing agent gas flow path for supplying the oxidizing agent gas to each said unit cell, all of the first gap region and the second gap region fluidly communicate with one another, said oxidizing agent gas flow path consisting of said all of the first gap region and the second gap region communicating with one another, and each said unit cell is a direct methanol fuel cell or a polymer electrolyte fuel cell.
