Abstract

PURPOSE:To keep phosphoric acid of electrolyte to higher temperature than its freezing point by covering the outer surface of fuel cell main body with heat insulating material and arranging a heater in the fuel cell main body. CONSTITUTION:Four heaters 7 arranged so as to surround four sides of a cooler 4 are connected in series with a wire 8, and connected to a power source 9 arranged outside a fuel cell main body 5. When the fuel cell 5 is transported or installed, valves 4b and 4c are demounted from a cooling medium supply source, and hot water having a specified temperature is filled and valves 4b and 4c are closed. When the power source is turned on, four heaters are heated and temperature reaches a specified value, and the power source is turned off. When the temperature inside the fuel cell 5 is decreased with the time elapsed, the power source is turned on. Therefore, phosphoric acid solution is always kept to higher temperature than its freezing point.

However, while this battery is functioning, the inside of the fuel cell main body (5) is maintained at a temperature suitable for power generation by the cooler (4), but when transporting it or celebrating, etc. Naturally, the above-mentioned reaction does not occur and the temperature inside the fuel cell main body (5) decreases because no heat is generated. For this reason, in the past, hot water was sealed in the cooler (4) to prevent the temperature from dropping. The temperature decreases due to heat dissipation from the phosphoric acid aqueous solution, reaching the freezing point of the phosphoric acid aqueous solution (100% phosphoric acid 42.4°C), and the solidified resin crystals damage each electrode due to vibration, reducing the lifespan of the fuel cell. It had the disadvantage of giving rise to
