摘要： The IR resistance of each unit cell 2 is measured (step S14), and a highest unit cell voltage as a threshold voltage is set based on the IR resistance and the load current (step S18). The setting of the highest unit cell voltage uses map data that approximates current-voltage characteristics of a unit cell when the fuel gas is insufficiently supplied. In that case, the highest unit cell voltage is determined based on the voltage with respect to the load current obtained from the map data, and the IR loss calculated from the IR resistance and the load current. This highest unit cell voltage is compared with the measured unit cell voltage (step S22). If the unit cell voltage is below the highest unit cell voltage, the power generation of the fuel cell is stopped or restrained (step S24).

摘要： In a stack of non-circulating-type fuel cells 20 where a supply of a fuel gas is not recirculated, a control circuit 50 sets a changeover valve assembly 41 in a disconnected state from both high-pressure hydrogen tanks 30 and outside of a cell stack body 21, while setting residual changeover valve assemblies 40, 42, and 43 in a connecting state to connect inside of the cell stack body 21 with the high-pressure hydrogen tanks 30. The supply of the fuel gas is accordingly fed into the stack of fuel cells 20 via the changeover valve assemblies 40, 42, and 43 and goes through electrochemical reactions. An impurity-containing gas after the electrochemical reactions is accumulated in the vicinity of a connection port 22. The control circuit 50 then sets the changeover valve assembly 41 in a connecting state to connect the inside of the fuel cells 20 with the outside and discharge the impurity-containing gas to the outside of the fuel cells 20. The control circuit 50 sequentially changes over the changeover valve assemblies 40 to 43 to the connecting state and thereby prevents the impurity-containing gas from being accumulated in the vicinity of any specific connection port. This arrangement desirably restrains potential deterioration of power generation performances of fuel cells and enhances the durability of the fuel cells.
