SOURCE OF CURRENT WITH SERIES CONNECTED CELLS

摘要

The invention relates to several cells for current generation, especially fuel cells that are connected in series. Diodes are connected in parallel to said fuel cells in such a way that current (I) generated by the fuel cells cannot cause any short circuit. If one of the cells fails as a result of a defect, the current flows through a parallel-connected diode due to the fact that the diodes then form the low ohmic resistance. In case of a failure, this makes it possible to automatically short-circuit the defective cells in a simple and economical manner.
