FUEL CELL UNIT FOR USERS CONNECTED TO A RECHARGEABLE BATTERY

摘要

Fuel cell units are suitable for continuous energy supply to electrical user s in a particular manner. Particularly for the application in motor vehicles t he above can either be the drive for an electric motor and/or also the supply o f other electrical users. According to the invention, a fuel cell module (10) only delivers the electrical energy to a rechargeable battery (5) and not directly to the user (1). The fuel cell module (10) can thus be permanently held at the optimal operating point thereof. Said fuel cell module (10) preferably comprises HT-PEM fuel cells, which in contrast to PEM fuel cells work at a higher temperature, in particular in the range 120 ~C to 200 ~C.
