ABSTRACT:
A fuel-cell evaluation equipment includes a gas passageway for supplying gas to a fuel cell and a thermostat adapted to accommodate the fuel cell, wherein the gas passageway includes a first temperature regulator adapted to regulate the temperature of gas and a humidity regulator adapted to regulate the humidity of the gas. A thermostatic chamber of the thermostat regulates an inner temperature in the chamber according to a test condition. The thermostatic chamber is provided with a second temperature regulator into which gas flowing in the gas passageway flows. The gas flowing in the gas passageway is supplied to the fuel cell after heat exchange by the second temperature regulator.
