Abstract

PURPOSE:To prevent air passages in each unit cell from being clogged, by thermally insulating or heating an air-pole exhaust passage for preventing water vapor from condensing at the outlets of an air-pole chamber. CONSTITUTION:Air as an oxidizing agent is supplied into stacks 2 and 2' of a fuel cell through oxidizing-agent supplying passages 4 and 4' and discharged to the atmosphere through an exhaust passage 5 provided between the stacks 2 and 2'. The oxidizing agent supplying fans 4 and 4' are contacted with the open air and therefore the wall faces thereof have a temperature close to that of the open air. The exhaust passage 5 which is interposed between the fuel cell stacks 2 and 2', however, the temperature thereof is maintained approximately at an operating temperature of the fuel cell. Accordingly, water vapor contained in the exhaust air will neither be condensed at the air outlets 6 and 6' in each unit cell nor cause the oxidizing agent passages to be clogged.

った。Conventionally, fuel cells have used methods such as releasing exhaust from the air electrode directly into the atmosphere, or by providing an exhaust passage and releasing it all at once. However, in this method, 100℃
In fuel cells operated under the following conditions, water vapor contained in the air electrode discharge condenses at the air electrode chamber outlet, clogging the air passages of each cell and impairing the air electrode characteristics. Ta.

本発明ハ、−、ヒ配の欠点を除去するものである。The present invention obviates the drawbacks of the following.

防ぐことによって空気極特性の損失を防ぐものである。In order to achieve the above object, the present invention maintains or warms the air electrode discharge passage to prevent water vapor from condensing at the outlet of the air electrode chamber, thereby preventing clogging of the air passage in each unit battery. This prevents loss of air electrode properties.
