Abstract

The invention relates to a power supply device (1) having a plurality of fuel cell units (12) arranged in parallel strands (50, 60, 70), wherein each strand (50, 60, 70) has at least two fuel cell units (12) connected in series or at least two groups (13, 13'), connected in series, of fuel cell units (12). According to the invention, the strands (50, 60, 70) are interconnected in each case at a node point by means of at least one cross connector (90, 90', 90'', 90'''), wherein the node points (92, 92') are formed between two fuel cell units (12), connected in series, of a strand (50, 60, 70) or between two groups (13, 13') of fuel cell units (12) of a strand (50, 60, 70).
