Abstract
The present invention is to properly adjust a water content in a cell of a fuel cell in response to a wide variety of conditions. A method of controlling a water content in a cell of a fuel cell, wherein a flow rate and pressure of a hydrogen gas supplied to an anode electrode of the cell of the fuel cell are adjusted so as to satisfy a restrictive condition in order to control a water content in the cell of the fuel cell. A water content state in the cell is detected and, based on the detection result, a flow rate and pressure of the hydrogen gas are adjusted so that a water content in the cell equals a target water content.
