Abstract
A fuel cell stack comprises a stack of three or more fuel cells, each having an assembly in which an anode electrode and a cathode electrode are respectively joined to either side of an electrolytic membrane. The anode electrode is provided nearer to one end, in the stack direction of the fuel cell, than the cathode electrode. Temperature regulating parts for regulating the temperature of the anode electrode of one fuel cell of any two adjacent fuel cells and the cathode electrode of the other fuel cell are disposed at a plurality of positions arranged in the stack direction. The provided temperature regulating parts perform temperature regulation so that the heat dissipating capability of the anode electrode is different in the stack direction from that of the cathode electrode.
