FUEL CELL SYSTEM AND POWER GENERATION MONITORING METHOD

摘要

A fuel cell system comprising: an acquirer that acquires a total value of cell voltages of two or more cells included in a fuel cell; and a determiner that determines, when the total value is a first voltage value, abnormal power generation in which power generation by at least a part of the two or more cells is abnormal, that determines, when the total value is a second voltage value higher than the first voltage value, normal power generation in which power generation by the two or more cells is normal and that determines, when the total value is a third voltage value higher than the first voltage value but lower than the second voltage value, the normal power generation if a cathode gas is deficient or the abnormal power generation if the cathode gas is not deficient.

1. A fuel cell system comprising:
an acquirer that acquires a total value of cell voltages of two or more cells included in a fuel cell; and a determiner
that determines, when the total value is a first voltage value, abnormal power generation in which power generation by at least a part of the two or more cells is abnormal,that determines, when the total value is a second voltage value higher than the first voltage value, normal power generation in which power generation by the two or more cells is normal andthat determines, when the total value is a third voltage value higher than the first voltage value but lower than the second voltage value, the normal power generation if a cathode gas is deficient or the abnormal power generation if the cathode gas is not deficient.
