本発明は、燐酸電解質を用いる燃料電池特に可搬用小型
電池の停止保存方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for shutting down and storing a fuel cell, particularly a small portable battery, using a phosphoric acid electrolyte.

保温を行なう目的は、電池の安全性確保と電解質の変質
防止のためである。When shutting down a fuel cell, conventionally, the cell temperature is lowered by forced circulation of outside air, and then a nitrogen purge is performed to replace the cell and each reaction gas in the path with nitrogen gas, and an electric heater is used to lower the cell temperature to 110°C to 120°C. It was kept warm and preserved. The purpose of nitrogen purging and heat retention during storage is to ensure the safety of the battery and to prevent deterioration of the electrolyte.

保温することは不可能となる。However, portable batteries (several KW to several tens of KW output)
The place where this is used is where commercial 'Wt, /lX and nitrogen gas are not available, and it is impossible to keep it warm by electricity while performing the conventional nitrogen purge.

保存を行なうものである。This invention provides external fresh air to the reaction air system and cooling air system when the battery is stopped. With the supply of fuel gas cut off, the hydrogen partial pressure in the fuel gas is lowered by a discharge reaction to cut off the afterload, and fresh air is then passed through the fuel system, allowing the battery to reach a predetermined temperature. When it drops to
The supply/exhaust valves of the fuel system, reaction air system, and cooling air system are closed to fill each prefecture in the battery with fresh air, and the battery is stored in this state.

2) The afterload is cut off by discharging the battery until it drops, and external fresh air is circulated through this fuel system in the same way as the reaction air system and cooling system, and external fresh air is sealed in each prefecture in the rear battery. This eliminates the need to perform a nitrogen gas purge as in the past, and even if the temperature of the battery drops to the outside temperature, only a limited amount of moisture in the enclosed air will be absorbed by the electrolyte, causing major damage to the battery. This eliminates the need for nitrogen purge or heat insulation using electric heaters, making it possible to store portable fuel cells even in locations without commercial power or nitrogen sources.
本発明の実施例を第１図につい工説明する。An embodiment of the present invention will be explained with reference to FIG.

Hydrogen-rich gas (8280%,
Using CO2 (20%), a battery reaction occurs with reaction air as an oxidizing agent to generate electricity. At this time, the fuel gas and reaction air supply and aeration valves (3) (3') and (

A part of the high-temperature exhaust gas that cooled the battery (1) is transferred to the battery (1) as reaction air.

In addition to the valves (7) and (7'), it has an outside air intake valve (8) and an external exhaust valve (9).The external exhaust valve (9) is closed during battery operation, but when the outside air intake valve (8) is closed. When opened, the low-temperature fresh air introduced through this valve (8) supplements the air that can be exhausted as reaction air and lowers the temperature of the cooling air circulating through the battery.
次に電池の運転停止及び保存法について説明する。Next, methods for stopping and preserving the battery will be explained.

3') is closed. At the same time, the external exhaust valve (9) is opened, and the external fresh air taken in from the outside air intake valve (8) flows through the oven path to the cooling system to cool the battery (1), and also flows to the reaction air system. The hydrogen partial pressure in the fuel gas sealed between valve 3) (3'), which sends the moist air inside the battery out of the system, decreases due to the reaction with the reaction air, and this drops to a predetermined value. This is detected by the battery T pressure and the load (10) is cut off.Then, the branch valve (11) and the exhaust valve (3') are opened to allow external air to flow through the fuel system as well, allowing fuel with low hydrogen partial pressure to flow through the fuel system. Exhaust the gas directly out of the system.

により、電池（１）内の各県に外部空気を封入する。Thus, the outside air flowing through the oven path through the fuel system, reaction air system, and cooling system lowers the cell temperature.5. When the temperature drops to a certain level (approximately 120°C), the blower (5) is stopped and the six supply/exhaust valves (11 valves (3
'), (4>(4') and (7) By closing (7'), external air is sealed in each prefecture in the battery (1).

くは電解質の増量はわずかである。Storage is carried out in this state, but the battery temperature gradually drops to the outside temperature, and since the phosphoric acid in the electrolyte is hygroscopic, the fuel system and reaction air system absorb moisture from the enclosed air and the phosphoric acid concentration decreases. Since the amount of air enclosed is small, there is only a slight decrease in concentration or increase in the amount of electrolyte.

Resulting in bulk increase and possibly freezing. In order to withstand these conditions, as shown in Figure 2, the electrolyte matrix (M) is made of a strong carbon matrix layer (mI) (ml) made of Si.
A carbon plate (12>) is arranged on both sides of the C matrix layer (m2) to form a three-layer structure, and has flow grooves (13) and (14) for the fuel gas and reaction air.

。According to the present invention, when the oven is stopped, the hydrogen partial pressure in the fuel gas system is reduced to cut off the afterload while the external air is flowing through the oven path to the reaction air system and the cooling air system. External air is also circulated through the system, and when the battery temperature drops to a predetermined value, external air is sealed in each part of the battery to preserve it. It eliminates the need for continuous supply into the system and continuous energization of temperature-maintaining heaters, making it possible to stop and store the battery without causing any trouble to the battery even in places where there is no commercial power supply or nitrogen/power supply. It is extremely effective for portable fuel cells.
