A fuel gas and an oxygen containing gas are supplied downwardly through different passages into a first manifold plate 42, a first surface pressure generating plate 44, a separator body 48, a second surface pressure generating plate 46, a second manifold plate 50, a first gasket 30, a solid polymer

A fuel gas and an oxygen containing gas are supplied downwardly through different passages into a first manifold plate 42, a first surface pressure generating plate 44, a separator body 48, a second surface pressure generating plate 46, a second manifold plate 50, a first gasket 30, a solid polymer electrolyte membrane 22, and a second gasket 32, into which cooling water is supplied upwardly. The cooling water rises upwardly in the separator body 48 to reduce a temperature distribution in a fuel cell 20.

[ What is claimed is:] [1.]1. A method of controlling a fuel cell having a horizontal stack of fuel cells each having an anode electrode and a cathode electrode which sandwich an electrolyte membrane and which are sandwiched by separators, comprising the steps of supplying an oxygen containing a gas in a direction of gravity to the cathode electrode, and supplying a cooling medium into said separators in a direction opposite to the direction in which the oxygen containing gas flows, wherein the cooling medium minimizes a temperature distribution within the fuel cell, thereby improving operation of the fuel cell.
