摘要： PROBLEM TO BE SOLVED: To accurately diagnose causes for decreasing the output of a fuel cell.
SOLUTION: Current flowing through a part that is easily dried in the fuel cell 10 is measured by current measuring means 132, 133, 164, 165, 172, and 173. When the current is less than a specified current value, the fuel cell 10 is diagnosed to be in a dry state. Additionally, current flowing through the part in which moisture tends to become excessive in the fuel cell 10 and hydrogen easily lacks is measured by current measuring means 134, 166, and 174. When the current is less than a specified current value and a decrease speed in the current is less than a specified decrease speed, the fuel cell is diagnosed to have surplus moisture. When the current is less than the specified current value and the decrease speed of current is equal to or more than the specified decrease speed, the amount of supply of hydrogen to the fuel cell is diagnosed to be in shortage.
