A fuel cell arrangement comprises a fuel cell current source, peripheral units, a regulated hydrogen source for the fuel cell current source, based on the hydrolysis of a hydride and furthermore an electronic control circuit for controlling the fuel cell current source and an electronic control circuit for controlling the hydrogen source. The control circuit, for the fuel cell current source and the control circuit, for the hydrogen source are coupled together and the control of the current source and the hydrogen source carried out with mutually related adjustment.
