A device for improving the electricity-generating performance of a fuel cell system which comprises a crystallization promoting device is provided to filter NaBO2 in activated state for crystallization so as to prevent gelation of NaBO2 crystals, and to prevent clogging of piping lines and degradation of the electricity generating performance in the fuel cell system. The device for improving the electricity-generating performance of a fuel cell system(100), wherein the fuel cell system comprises: a fuel tank(102) which contains BH4- as an aqueous solution; an electric generator(101); a fuel supply line(103) to supply BH4- to the anode of the electric generator, which comprises a fuel supply pump(105); a fuel collecting line(104); an air supply line(106) formed on the cathode of the electric generator, which comprises an air compressor(108); and an air exhaust line(107), comprises: a device(110) for promoting BO2 crystallization of the fuel recovered from the fuel collecting line to the fuel tank, by being formed between the generator and the fuel tank, wherein the device may be a thermoelectric element; and a filter(111) to filter out the crystallized BO2, by being formed after the device for promoting BO2 crystallization. |
