A fuel cell module includes a fuel cell stack formed by stacking a plurality of fuel cells for generating electricity by electrochemical reactions of a fuel gas and an oxygen-containing gas, a reformer for reforming a mixed gas of a raw fuel and water vapor, an evaporator for supplying water vapor to the reformer, a heat exchanger for raising the temperature of the oxygen-containing gas by heat exchange with a combustion gas, an exhaust gas combustor for producing the combustion gas, and a start-up combustor for producing the combustion gas. The exhaust gas combustor is provided integrally in the heat exchanger. The start-up combustor is provided adjacent to one end of the heat exchanger.

Fuel cell module

A fuel-cell system with a fuel battery comprising more than one fuel cell having a purge gas passage connecting the fuel battery to a purge gas cylinder, a discharge passage connecting the fuel battery to the exterior, solenoid valves each installed in the passages, and an electronic control unit that opens the solenoid valves to open the passages to supply the purge gas to the fuel battery such that residue in the fuel battery is purged to the exterior by the purge gas. The control unit opens the valves at a time interval determined from an output of a current sensor to conduct purge at optimum timing for the battery operating state so as to prevent accumulation of residue in the fuel battery, while preventing repetition of unnecessary purges. Alternatively, manual valves are provided to be manually opened by an operator to open a fuel gas supply passage to supply the fuel gas such that residue is purged by the fuel gas through the discharge passage, thereby enabling fuel supply and purge of residue at starting of power generation, without using an external power source.

The current collectorsandare formed of a corrosion resistant conductive material. The electrodesandare formed of a porous material containing a conductive powder.

Electrolytic cell for electrolyzed water generator

A first electrolytic chamber which houses an anode plate and a cathode plate with an ion-permeable membrane interposed therebetween is supplied with raw water containing an electrolyte as chloride ions. The raw water is electrolyzed to obtain electrolyzed water at a cathode side in the first electrolytic chamber. The electrolyzed water is then electrolyzed at an anode side in a second electrolytic chamber which houses an anode plate and a cathode plate with an ion-permeable membrane interposed therebetween, for thereby generating hydroxyl radicals in the electrolyzed water. The electrolyzed water containing the hydroxyl radicals is added to water containing an organic substance to cause the hydroxyl radicals to attack to the organic substance for thereby decomposing the organic substance.
