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.

Fuel-cell evaluation equipment

A temperature regulator has two headers connected to both ends of a heat receiving tube in which gas flows. The heat receiving tube has a heating element at the outer periphery thereof and a mixer accommodated therein to cause turbulent flow of gas passing through the heat receiving tube. The headers each have fins radially attached thereto, thereby ensuring strength of the headers and improving heat exchange efficiency.
