Polymerelektrolyt-Membran-Brennstoffzelle

The invention relates to a PEM fuel cell, consisting of at least one strip diaphragm (8) which consists of at least 2, maximum 10,000 flat individual cells each comprising an electrode layer (10-12, 13-15) applied on both sides of a diaphragm made of polymer fixed electrolytes, whereby the individual cells are switched in series and are made of non-conducting material plates (21, 22) which act as heat exchangers and fuel supply device, which are contacted on the strip diaphragm (8, 16) on both sides and separate conductive structures (23,24) routed externally to the voltage tap
