Embodiment approach 2

[0077] The fuel cell power generation device according to Embodiment 2 has substantially the same configuration as the fuel cell power generation device according to Embodiment 1, but as Figure 4 As shown, the cooling water piping 8 is characterized in that there are blocking parts 41A and 41B for blocking the flow of cooling water between the fuel cell 1 and the heat exchanger 10 . Although the case where two cutting parts are provided is shown here, one may be used, and the effect will be enhanced when a plurality of them are provided.

[0078] Figure 4 It is a figure which schematically shows the cutting|disconnection part 41A used in this embodiment. The cutout portion 41B may also have the same structure. Such as Figure 4 As shown, the blocking portion 41 is configured by connecting the inlet pipe 8A and the outlet pipe 8B to the main body container 8C. The inlet pipe 8A is connected to the upper portion of the main body container 8C, and the outlet pipe 8B is conn...

[0085] "Example 1, 2 and Comparative Example"

[0086] In this example, a figure 1 The fuel cell power generation device 1 (Example 1) of the structure shown has the following image 3 A fuel cell power generation device 2 (Example 2) having the structure shown and a comparative fuel cell power generation device (Comparative Example) as shown in FIG. 7 are shown.

[0087] First, a single cell of the fuel cell 1 was fabricated. A catalyst body (50% by weight of platinum) was obtained by carrying a platinum catalyst on the surface of carbon powder (denkabrak FX-35 manufactured by Denki Kagaku Kogyo Co., Ltd.), and the catalyst body was dispersed in the alcohol of the polymer electrolyte. solution (Flemion FSS-1 manufactured by Asahi Glass Co., Ltd.) to obtain a slurry.

[0088] In addition, a carbon paper with a thickness of 200 μm (TGP-H-090 manufactured by Toray Co., Ltd.) was immersed in an aqueous suspension of polytetrafluoroethylene (PTFE), and dried and heat-treated t...

Abstract

The present invention is to realize a fuel cell power generator capable of maintaining the electroconductivity of cooling water at a low level for a long period of time, preventing the metal member contacting the cooling water from corroding, and functioning without causing any harm to power generation. In the fuel cell power generator comprising a fuel cell, a cooling water pipe, a heat exchanger and a means for circulating cooling water, the formation of a conductive network electrically connecting the fuel cell, the cooling water pipe, the heat exchanger and the means is prevented.

Description

technical field [0001] The present invention relates to a fuel cell power generation device capable of suppressing deterioration in the quality of cooling water of a fuel cell. Background technique [0002] Since the polymer electrolyte fuel cell operates at around normal temperature, it is expected to be used in households and other civilian applications. Such a fuel cell is used not only for power generation at the installation site but also for a combined heat and power system that utilizes exhaust heat. [0003] The basic cell unit of a polymer electrolyte fuel cell is an electrolyte membrane electrode assembly (MEA) composed of a pair of gas diffusion electrodes sandwiching a polymer electrolyte membrane (thickness 30-100 μm) having hydrogen ion conductivity. [0004] The gas diffusion electrode is the same as the polymer electrolyte membrane, and the gas diffusion base material is coated with a mixture of an electrolyte resin having hydrogen ion conductivity and carbo...
