PURPOSE:To decrease heat loss and simplify an apparatus by conducting heat exchange and humidity exchange at the same time by passing an air supply system and an air exhaust system of fuel cell main body through one temperature-humidity exchanger. CONSTITUTION:Supply air to a fuel cell main body 6 which generate electric power by reacting air and hydrogen rich gas is passed into a temperature-himidity exchanger 12 after controlling the flow rate with flow rate control systems 1, 2, and 3, and supplied to an air electrode after conducting heat exchange and humidity exchange with air converted to high humidity and high temperature by reaction. Pressure is controlled to specified with pressure control systems 7, 8, and 9 on the outlet side of the cell main body 6. After reacting with air, air is passed again into the temperature-humidity exchanger 12 to conduct heat exchange and humidity exchange with air of low temperature-low humidity, then exhausted. Therefore, because, by one heat exchange, humidity exchange is performed at the same time, heat loss is decreased and an apparatus is simplified. |
