Power system for fuel cell, electronic equipment and electric power feeding method

摘要: As disclosed, there is provided a small-size power system for fuel cell allowing efficient extraction of electric power-output from and secondary cell, electronic equipment, an feeding method. The has voltage conversion circuit rectification circuit, structured such that output the converted with set voltage, which corresponding to maximum as reference produce switch at least either or outputted through circuit. This allows parallel operation in state can be utilized full.
