This paper analytically compares three types of regulated power supplies for new fuel cells. In the near future, telecommunication systems will make use of fuel cells. The fuel cells must have their output voltage regulated. The comparisons are based on the efficiency of the regulated power supplies. The results show that the chopper-type and the boost-converter-type power supplies are better than the converter-type one as regards efficiency. Furthermore, the efficiencies of the chopper-type and the boost-converter-type power supplies are high when the difference between the output voltage of the fuel cells and the output voltage of the power supply is small.
