A controll board specially laid out for the control of fuel cell systems has been designed. The board is able to be used for a bandwidth of fuel cell system architectures and allows an easy programming of control strategies. Data akquisition, control signals and communication moudles are integrated on the board. Programming of the Atmega128 processor is possible using Matlab-Simulink.
