The invention relates to a PEM fuel cell comprising at least one strip meane (8) which itself comprises at least 2, and a maximum of 10,000-surfaced individual cells each comprising an electrode layer (10-12, 13-15) applied on both sides of a membrane made of a polymeric solid electrolyte, the indiv

The invention relates to a PEM fuel cell comprising at least one strip meane (8) which itself comprises at least 2, and a maximum of 10,000-surfaced individual cells each comprising an electrode layer (10-12, 13-15) applied on both sides of a membrane made of a polymeric solid electrolyte, the individual cells being incorporated in series and being made of plates (21, 22) of non-conductive material, which serve as heat exchangers and as fuel gas supply device, which are contacted on both sides on the strip membrane (8, 16) and separate outwardly-directed conductive structures (23, 24) for voltage derivation.
