PURPOSE:To provide a fuel cell cooling plate, which can make uniform the intra-battery plane temperature without causing drop of the power generating efficiency. CONSTITUTION:An air-cooling type fuel cell is equipped with a cooling plate 6, which makes heat exchange between the fuel gas supplied to the anode 2 of the cell and the cooling air to cool the reaction heat generated from reaction with the reaction air to be supplied to the cathode 3 and which exhausts the heat to outside the cell, wherein the cooling plate is formed with a plurality of materials having different thermal conductivities and the cooling air supply side is made of a material having a smaller thermal conductivity than the cooling air exhaust side. |
