Embodiment approach 1

[0060] figure 1 The shown fuel cell water treatment device 10 includes a cartridge filled with an ion exchange resin. There can be one or more barrels. The ion exchange resin filled in the barrel is an anion exchange resin, or a mixed bed resin of anion exchange resin and cation exchange resin. Wherein, in the water treatment device 10 of the fuel cell, a cylinder filled with activated carbon or the like may be additionally provided in addition to the cylinder filled with the ion exchange resin.

[0061] The fuel cell water treatment device 10 of the present embodiment is mainly used to remove impurity ions in water supplied to the fuel cell 12 . As the water treated by the water treatment device 10 of the fuel cell, tap water (municipal water supply), pure water, condensed water generated by the power generation reaction of the fuel cell 12, etc. may be used.

[0062] Municipal water such as tap water is delivered to the water treatment device 10 of the fuel cell through t...

Embodiment approach 2

[0084] figure 1 The shown fuel cell water treatment device 10 has a cartridge filled with an ion exchange resin. There may be one cylinder or multiple cylinders. The ion exchange resin packed into the cartridge is an anion exchange resin, or a mixed bed resin of anion exchange resin and cation exchange resin. In addition, the fuel cell water treatment device 10 may additionally include a cylinder filled with activated carbon or the like in addition to the cylinder filled with the ion exchange resin. A water treatment device for a fuel cell needs to be heat-resistant and capable of being miniaturized. For example, JP-A-11-204123 discloses an example of using an anion exchange resin having a plurality of hydrocarbon groups in order to improve heat resistance. In addition, for example, JP-A-8-17457 discloses an example of optimizing the amount of cation exchange resin packed in a mixed-bed resin column in order to reduce the size of the device.

Embodiment approach 3

[0110] figure 1 The shown fuel cell water treatment device 10 may be equipped with a cartridge filled with ion exchange resin. There can be one or more barrels. The ion exchange resin filled in the cylinder is mainly a mixed bed resin of anion exchange resin and cation exchange resin, but if the cylinder is also installed on the upstream side, it can also be other anion exchange resins, or cation exchange resins, etc. single bed. In addition, the fuel cell water treatment device 10 may additionally include a cylinder filled with activated carbon or the like in addition to the cylinder filled with the ion exchange resin. In the mixed bed resin of cation exchange resin and anion exchange resin according to this embodiment, the average particle diameter of the cation exchange resin is preferably 0.2 mm or more and preferably 80% or less of the average particle diameter of the anion exchange resin. As explained above, since the specific gravity of the cation exchange resin and ...

Abstract

The invention provides a water treatment facility for fuel cell capable of effectively reducing the concentration of chloride ions in water supplied to the fuel cell. The water treatment facility adopts ion exchange resin which contains anion exchange resin. The proportion of chloride ions in the whole exchange capacity of the anion exchange resin in a primary state is less than 10%.

Description

technical field [0001] The present invention relates to a fuel cell water treatment device using an ion exchange resin. Background technique [0002] Fuel cells require hydrogen, and in order to produce hydrogen from city gas or natural gas, water needs to be used in the modification process, and pure water is used for the water. In addition, pure water needs to be used when cooling the fuel cell or when humidifying the polymer membrane of the solid polymer fuel cell. [0003] Pure water is usually produced by removing impurity ions through a water treatment device equipped with ion exchange resins. In addition to the technology of producing pure water from tap water, there are various technologies for treating condensed water generated from the power generation reaction of the fuel cell and recycling the treated water (pure water) to the fuel cell. [0004] For example, Patent Document 1 discloses a technique in which carbonate ions and bicarbonate ions (hereinafter refer...
