JPS595572A - Fuel supply method for liquid fuel battery - Google Patents

Abstract

PURPOSE:To eliminate the need for a cylinder and reduce the weight and volume and then uniformly supply liquid fuel to the fuel chamber of each unit battery by providing a fuel pump and an electromagnetic opening and closing valve while being linked directly with the laminated battery of a liquid static type liquid battery and a pressure regulating valve at the reverse side. CONSTITUTION:Since liquid fuel is stored in a fuel tank 1 and an electromagnetic opening and closing valve 3 is opened usually, the liquid fuel supplied by a fuel pump 6 is not supplied to a laminated battery 4, but it passes through a bypass. When the liquid fuel in the laminated battery 4 is consumed, the electromagnetic opening and closing valve 3 is closed. The liquid fuel is pressurized to the pressure preset by a pressure regulating valve 7 and supplied to the fuel chamber of each unit battery in the laminated battery 4. When the battery voltage is restored up to the normal value and the fuel concentration in the fuel chamber is restored to the preset value, the electromagnetic opening and closing valve 3 is opened and the supply of the liquid fuel is stopped. That is, since pressurized gas is not required for fuel supply, any high pressure cylinder is not required.

Description

[Detailed Description of the Invention] The present invention provides a mixed solution of fuel and electrolyte (hereinafter referred to as "anolyte").
1°) into the furnace material chamber, the electrolyte into the electrolyte chamber,
The present invention relates to a method of supplying fuel to a static liquid fuel cell that supplies only fuel to a fuel chamber.

Liquid stationary liquid F fuel cells do not have a system for circulating anolite like conventional liquid fuel cells, so w'F+ cannot be pumped into the anolite and supplied into the cell, and only liquid fuel is used. A method has been adopted in which fuel is supplied under pressure to the fuel chamber. FIG. 1 is a system diagram showing a conventional method of supplying liquid fuel used in the operation of a stationary liquid smoking cell.

The liquid fuel stored in the fuel tank 1 is pressurized by an inert gas 2, and by opening and closing the electromagnetic on-off valve 3, the liquid fuel is supplied to the stacked battery 4. Air (oxygen) required for the reaction is supplied to the stacked battery 4 by an air blower 5.

This conventional method requires a cylinder when the storage pressure of the tank storing the inert gas 2 is high, so when a liquid stationary liquid fuel cell is put into practical use, it has the disadvantage of an increase in weight and volume. 1. The present invention connects the fuel tank and the fuel pump directly to the stacked battery of the stationary liquid fuel cell in the above order, and furthermore, connects the electromagnetic on-off valve to the bypass of the paddy bomb to Providing a pressure regulating valve on the opposite side of the supply eliminates the drawbacks of the conventional method.

FIG. 2 is a system diagram showing a method of supplying liquid fuel in a stationary liquid fuel cell according to the present invention.

Liquid fuel is stored in a fuel tank 1, and is usually operated by an electromagnetic on-off valve 3.
Since it is open, the liquid fuel supplied by the fuel bomber is not supplied to the stacked battery 4 and passes through the Ibus. Now, when the liquid fuel in the stacked battery 4 is consumed, the electromagnetic on-off valve 3 closes, and the liquid smoke f-1 is pressurized to the set pressure by the pressure horn adjustment valve 71 and stacked.
! ! One furnace feed chamber for each W battery in the pond 4 is supplied. When the battery voltage returns to the normal rl value, but the furnace concentration in the W1 chamber recovers to a predetermined value, the electromagnetic on-off valve 3 opens and rl.
The supply of liquid fuel 1 is stopped.By using the present invention, the weight and volume can be reduced, and moreover, the liquid fuel is uniformly supplied to the fuel chamber of each intermediate battery, so a stable electrical output can be obtained. There are seven advantages, so the commercial value of practical application is extremely low.
