Abstract
An electric power source arrangement is described, comprising a fuel cell means () having a nominal voltage and a specified voltage-current characteristic, to be connected to a load (), and comprising a variable DC-DC voltage converter (), a by-pass branch () by-passing the DC-DC voltage converter, a switch () alternatively connecting the fuel cell to the DC-DC voltage converter or to the by-pass branch, and a control unit () controlling the switch, which control unit () comprises a measuring device coupled to the fuel cell means () for detecting the operating point thereof and is configured to connect the by-pass branch () if the fuel cell means voltage is within a selected range of section () of the voltage-current characteristic of the fuel cell means and to disconnect the by-pass branch in the remaining range of sections () of said characteristic.
