Fuel cell stack with exhaust gases after-burning region at the periphery of the stack

摘要

The fuel cell battery has at least one air or oxygen-containing gas inlet point (25) for each cell and post-combustion occurs in an annular chamber around the cell stack.. The inlet points communicate as a whole or in groups via at least one air chamber (115) extending axially along the stack and in direct contact with it. Each air chamber is divided from a post-combustion chamber (4) by at least one dividing wall (40).
