BRENNSTOFFZELLENANLAGE UND VERFAHREN ZUM BETRIEB DERSELBEN

摘要

The fuel cell system has a fuel cell module [4] that consists of a number of cascaded part modules [4a,b,c]. A fuel gas chamber [26] of the last part module has a feedback line [R] for surplus coupled to the cathodes of the modules. This provides an exhaust gas free operation that avoids a potentially explosive condition.
