Fuel-cell evaluation equipment

A fuel-cell evaluation equipment comprising:

• a gas passageway for supplying gas to a fuel cell;
• and
• a thermostat adapted to accommodate at least a part of the fuel cell,
• wherein the gas passageway comprises a first temperature regulator adapted to regulate the temperature of the gas, a humidity regulator adapted to regulate the humidity of the gas, and a second temperature regulator,
• the first temperature regulator being provided with a heater adapted to heat gas and a cooler adapted to cool gas, and
• wherein the thermostat comprises a thermostatic chamber adapted to regulate the atmospheric temperature in the chamber into a predetermined condition,
• the second temperature regulator being provided with a heat exchanger located in the thermostatic chamber;
• wherein gas is regulated to a predetermined temperature and humidity by the first temperature regulator and humidity regulator and thereafter introduced into the heat exchanger in the thermostatic chamber so as to exchange heat with the thermostatic chamber.

• wherein the thermostat comprises a thermostatic chamber adapted to regulate the atmospheric temperature within the chamber into a predetermined condition, and
• wherein the second temperature regulator is provided with a heat exchanger and a heater,
• at least the heat exchanger being located in the thermostatic chamber,
• the heater of the second temperature regulator being deactivated when the following conditions are satisfied:
• (a) that a gas-flowing temperature of gas flowing into the second temperature regulator is lower than a preset temperature determined according to a test condition of a fuel cell,
• (b) that the difference between the gas-flowing temperature and the preset temperature is within a range capable of heating the gas to the preset temperature by heat exchange at the heat exchanger in the second temperature regulator in the thermostatic chamber, and
• (c) that gas flow into the second temperature regulator is less than a predetermined amount.
