却水により冷却している。(Prior Art) A fuel cell is a device in which hydrogen and oxygen are slowly reacted in a reactor using a catalyst, and the electricity generated during the reaction is used. The reaction between hydrogen and oxygen generates water and electricity, but it also generates heat of reaction. In order to maintain high power generation efficiency, it is necessary to maintain the temperature at 170 to 230'C, and the temperature is cooled with cooling water.

を排水する。A conventional fuel cell system will be explained with reference to FIG. Hydrogen and oxygen are supplied to reactor 1 of the fuel cell,
Air is generally used for oxygen and is supplied to the cathode. The cathode waste becomes a vapor and is sent to a cathode condenser 4 via a scrubber 2 and a heat exchanger 3 to drain the condensed water.

。Cooling water is sent into the reactor 1 to cool it, and is supplied to the reactor 1 after being purified by a filter 13 by a circulation pump 12. The cooling water leaving the reactor 1 is transferred to the gas-liquid separator 1.
A circulating system is formed in which steam and water are separated in step 4 and the water is sent to reactor 1 again. A portion of the cooling water in this circulation system is constantly treated to maintain water quality. The cooling water whose temperature has been lowered to 50 to 70°C in the heat exchanger 15 is
After being pretreated by the filter 16, the temperature is further lowered by a heat exchanger 17, and impurities are removed by an ion exchanger 18 and the like. The water to be treated is heated in a heat exchanger 15, degassed in a deaerator 19 by steam sent from the gas-liquid separator 14, pressurized by a pump 20, and returned to the circulation system.

いる。(Problems to be Solved by the Invention) In the above system, a portion of the steam separated by the gas-liquid separator 14 is constantly discharged for deaeration or as a heat source, so the amount of water in the entire cooling water system decreases. Therefore, city water, industrial water, pure water, etc. are used as make-up water. However, the cost of this make-up water is large, which poses a problem in terms of fuel cell efficiency.

。(Example) First, the quality of any or all of cathode condensed water, anode condensed water, and reforming system condensed water was analyzed. Condensed water generally contains iron, copper, nickel, chlorine, and other fuel cell-specific substances, including a large amount of fluorine. This fluorine is thought to be generated from fluorine compounds used in piping, electrolyte supports, etc. In addition to these, the condensed water contained a large amount of methanol, acids obtained by decomposing methanol (for example, formic acid), and compounds of methanol and other substances (for example, if ammonia is included, amines are produced). An investigation into the cause of methanol being generated in condensed water revealed that it was because the fuel sent to Reformer 5 was not only converted to hydrogen, but also partially converted to methanol. Reformer 5 contains a catalyst and has a high temperature, making it very suitable for producing methanol.
従ってメタノールの発生は避けられない。Therefore, generation of methanol is unavoidable.
