Brennstoffcellebatteri

摘要

The fuel cell battery has cells connected in series and is comprised an axially symmetrical stack of gas and air feed members and electrochemically active plates arranged alternately. Each feed member has an air heat exchanger in which the supplied air is heated. Gas and air may be made to flow in parallel on both ides of the electrochemically active plates. For each feed member, only one sealing ring is required to separate the air and gas spaces. The fuel cell battery has the advantage that induced stresses due to thermal expansion are small.
