摘要： Provided are a carbon powder which can provide a catalyst exhibiting high performance and a catalyst. A carbon powder for fuel cell comprising carbon as a main component, which has a ratio (B/A) of an area B of peak 1 to an area A of peak 0 of more than 0 and 0.15 or less, wherein the area A represents an area of peak 0 at a position of 2θ=22.5° to 25° as observed by XRD analysis when the carbon powder for fuel cell is subjected to heat treatment at 1800° C. for 1 hour in an inert atmosphere, and the area B represents an area of peak 1 at a position of 2θ=26° as observed by XRD analysis when the carbon powder for fuel cell is subjected to heat treatment at 1800° C. for 1 hour in an inert atmosphere.

摘要： Stacked bodies each formed by alternately stacking power generation cells and separators are fixed to an end plate, the separators each having a flow passage portion, a gas flow-in port, and a gas flow-out port. The end plate includes upper and lower end plates sandwiching the stacked bodies. The stacked bodies are arranged side by side and a first thermal deformation absorbing portion configured to absorb thermal deformation in a direction orthogonal to a stacking direction is formed between the stacked bodies. Fixing means for fixing the stacked bodies to the end plate fix at least outer peripheral portions of the stacked bodies arranged side by side to the end plate.

摘要： A fuel cell system includes: an external load connected to a fuel cell; an electric power adjusting unit configured to adjust a generated electric power of the fuel cell in accordance with electric power consumption of the external load; a humidity control unit configured to control humidity of an electrolyte membrane in the fuel cell on the basis of the generated electric power of the fuel cell; an output voltage detecting unit configured to detect an output voltage of the fuel cell; and a cross leakage determining unit configured to cause the humidity control unit to increase the humidity of the electrolyte membrane when the fuel cell generates the electric power, the cross leakage determining unit being configured to determine whether a cross leakage amount increases or not on the basis of a change in the output voltage at that time.
