Open the CIPO recordAbstract From the Canadian patent
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.
