摘要： PROBLEM TO BE SOLVED: To provide a new fuel cell system capable of increasing self-heat value of a cell without lowering the supply pressure of a fuel gas.
SOLUTION: If nitrogen stored in a nitrogen recoverer 35 is injected into air passing through an air passage 20, the oxygen partial pressure of the air supplied to a fuel cell 10 drops, and the IR loss of a cell increases. Therefore, self-heat value of the cell increases. Accordingly, warming-up of the fuel cell 10 is expedited by controlling so as to lower the oxygen partial pressure when the temperature of the fuel cell 10 is low for instance.

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.

摘要： PROBLEM TO BE SOLVED: To provide a current measuring device of a fuel cell where measurement errors generated by immersing into water of a columnar part and a current sensor can be reduced.
SOLUTION: In the current measuring device 20 that is arranged between cells 11 of the fuel cell, and that has a plurality of columnar parts 211, arranged corresponding to respective measurement positions in an electrode surface, and that has the current sensor for measuring the current flowing through these columnar parts, a first plate part 22b for waterproofing is arranged between the cell 11a on the left side and a current sensor plate 21, and a second plate part 22c for waterproofing is arranged between the cell 11b on the right side and the current sensor plate 21. At this time, a groove 23 for a cooling water passage is installed at these plate parts 22 for the waterproofing. Furthermore, for example, because the thickness of the plate part 22 for the waterproofing is made thin, a part 24 contacting the columnar part 211 of the current sensor plate 21 in the plate part 22 for the waterproofing is constituted of a conductor, and the other part 25 is constituted of an insulator, the surface resistance of the plate part 22 for the waterproofing is made larger than the resistance in the laminating direction.
