Fuel cell battery with integrated heat exchanger

摘要

The device has an integrated heat exchanger (4) with a channel system in which with the battery in an operating state the waste gas and oxygen carrier flow substantially in transverse planes perpendicular to cell stack axis, the waste gas is carried away by axial collection channels (47'') in a peripheral heat exchanger region and heat exchanger parts between this region and the cell stack screen the stack from collection channel thermal effects. AN Independent claim is also included for the following: a system with an inventive device and a control arrangement.
