    摘要: During the charging of a secondary battery, the charging current is maintained, but the value of the current is changed for a short time, and the internal resistance of the battery is calculated from the voltage and the current before and after the changing of the charging current. The charging voltage is determined by adding an extra voltage equivalent to the voltage drop caused by the internal resistance to a designated voltage. Thus, it takes only a short time for stabilizing the voltage when the current is changed, because the charging current is not switched off completely. Therefore, the charging time can be shortened.

    摘要: A fuel cell is provided which can control an optimum fuel concentration according to an output without a sensor for measuring the fuel concentration. The fuel cell uses a liquid organic compound for fuel and includes a membrane-electrode assembly, a passage for allowing fuel or oxidant to flow, a fuel supply unit for supplying the fuel to the fuel cell and intermittently or periodically changing a rate of fuel supply, and a computation processor for measuring a signal of a voltage or an output of the fuel cell, computing the rate of the fuel supply and the signal, and correcting the rate of the fuel supply. In the fuel cell, the optimum fuel concentration can be easily controlled according to the output by periodically varying the fuel concentration from a reference fuel concentration, measuring a voltage or an output and a variation range of the voltage or the output, and then determining whether the reference fuel concentration is appropriate or not.
