Electrical energy supply system for mobile platforms and vehicle having an electrical energy supply system

An electrical energy supply system for mobile platforms, the electrical energy supply system comprising:

• an electrical arrangement having at least two fuel cells, which are in a serial interconnection in relation to one another in the electrical arrangement along a single electrical current path, such that current flowing through the electrical arrangement passes sequentially through each of the at least two cells, the at least two fuel cells being configured to provide an electrical voltage to supply at least one consumer;
• a ground, which is assigned an electrical reference potential;
• and
• at least two controllers, each of which is assigned to at least one fuel cell of the at least two fuel cells, wherein each of the at least two controllers is configured to detect an electrical voltage of the at least one fuel cell to which the controller is assigned, in relation to the reference potential.
