Abstract (en)
[origin: DE19907369A1] The current source has a number of fuel cells (1) electrically connected in series, with a respective diode (2) connected in parallel across each fuel cell and providing a low ohmic resistance upon failure of the fuel cell, for preventing a short-circuit across the latter. An Independent claim for application of a current source in a portable electrical device is also included.
