And a return pipe 11 for returning a part of the treated water to the water tank 6 and a recovered water from the exhaust gas. Make-up water such as city water or industrial water is filtered by a filter device 7 using activated carbon or the like, and then passed through a treatment tank 8 using an ion exchange resin or a reverse osmosis membrane to obtain pure water having low electric conductivity. , To the fuel cell body 1.

Since the temperature of water used in the treatment device is usually about 30 to 50 ° C., which is an appropriate temperature for microbial propagation, the microorganisms propagate in the water tank 6, the filter device 7, the treatment tank 8 and the like, and the filter element and the ion exchange resin. Alternatively, there is a problem that it tends to adhere to the reverse osmosis membrane and cause a clogging accident. Therefore, it is necessary to frequently replace the filter element and wash the water tank 6, the treatment tank 8, etc. There was a drawback that continuous operation was not possible.

There is a risk of causing stress corrosion cracking of the existing piping and degrading the fuel cell catalyst, and the method of injecting ozone also degrades the ion exchange resin and reverse osmosis membrane. . Further, adding a device for completely removing the residual sterilizing agent or residual ozone to the preceding stage of the fuel cell main body 1 or the treatment tank 8 has a drawback that the device becomes large and causes a cost increase. In this respect, the ultraviolet sterilization method has a relatively small effect on the system, but since the sterilization system still needs to be inserted and added to the current system, there is a problem that the size of the device is increased and the equipment cost is increased. there were. The present invention has been made in view of the above problems, and an object thereof is to provide a structure of a water treatment device capable of suppressing the growth of microorganisms by an extremely simple and inexpensive method.

点がある。As described above, the present invention uses copper, zinc, lead, or an alloy containing these in the water passage portion of the water treatment device of a fuel cell, and the cations of these metals are dissolved in water. Therefore, these metal cations act as toxins for microorganisms and inhibit their reproduction, preventing the occurrence of clogging accidents due to the microorganisms adhering to the filter, ion exchange resin, etc. This enables long-term continuous operation without the need for regular cleaning work.
For the fuel cell body 1 and the fuel cell body 1, since the toxin component is only a trace amount of metal cations, the ion exchange resin and the fuel cell catalyst, which are polymer organic materials, are deteriorated as in the conventional method, or the piping is used. There is no danger of causing stress corrosion. Also in terms of cost, since the structure of the present invention does not require a special device, it can be provided at a lower cost than the one using a conventional ultraviolet sterilizer, and there is no risk of failure, and the installation location is small. There is an advantage that it does not.
