In a polymer electrolyte fuel cell, consumption rates of hydrogen gas and oxygen gas and a production rate of H_2O due to an electrochemical reaction were determined from the data of a current distribution in a MEA measured by a magnetic sensor. The amounts of the electro-osmotic dragging water with proton transport and the diffusion water from the cathode to the anode were also calculated with the experimental equations in the other's studies. Based on these values, the relative humidity of the fuel gas in the fuel cell was calculated. It was found that the relative humidity decreased after beginning of power generation. This calculated relative humidity was also close to the value measured by the laser interferometry.
