ABSTRACT:
A fuel cell evaluation apparatus of the present invention is provided with a fuel cell for generating electricity using fuel gas and oxidizer gas; a fuel gas supplying section for supplying the fuel gas; an oxidizer gas supplying section for supplying the oxidizer gas; an inert gas supplying section; a detector for detecting an amount of electricity generated by the fuel cell; a bypass for interconnecting a gas supply port of the fuel cell with a gas exhaust port of the fuel cell; three-way valves for switching the gas to either the fuel cell and the bypass; and a control section for controlling at least one of the three-way valves so as to replace the gas inside the fuel cell. The fuel cell evaluation apparatus and a fuel cell evaluation method of the present invention can evaluate the properties and performance of a fuel cell in a nondestructive manner.
