Abstract

PURPOSE:To reduce weight and volume and omit the replacement of an inert gas cylinder by adding a device that supplies fuel depending upon the load to the reforming device of a liquid static type liquid fuel battery or a gas fuel battery. CONSTITUTION:The liquid fuel stored in a fuel tank 1 is supplied by a fuel pump 6. Since an electromagnetic opening and closing valve 3 is closed when the fuel in a laminate battery 4 is full, the liquid fuel passes through a bypass and returns to the entrance side of the fuel pump 6 through a pressure regulating valve 7. In this case, the liquid fuel at the exit side of the fuel pump 6 is pressurized to the pressure preset by the pressure regulating valve 7. When current is applied to a load 8, the signal of a current detector 9 enters a control circuit 10 that is driven by the power of the laminated battery 4. The output represented by the function of current is supplied to the fuel pump 6 and the electromagnetic opening and closing valve 3 and the liquid fuel is supplied to the laminated battery 4. As a result, since the pressurized gas for fuel supply is not required, any high pressure cylinder is not required.

Description

[Detailed description of the invention] The present invention is based on a mixed solution of electrolyte and electrolyte.
It is called. ) to the material chamber, the electrolyte to the electrolyte chamber,
A stationary liquid that supplies only smoke to the fuel chamber can be converted into a fuel cell or a modified V containing hydrogen gas by reforming a liquid inertia such as methanol or ammonia into a gas. To,
The present invention relates to a method of supplying the m It depending on the load.

Unlike conventional liquid fuel cells, static liquid fuel cells do not have a system for circulating the anolite, so there are no methods for mixing smoke into the anorite and supplying it into the cell, and only liquid fuel can be used. A method is proposed 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 static liquid reactor fuel cell. C
The W fuel stored in the paddy tank 1 is pressurized by an inert gas 2, and by opening and closing the electromagnetic on-off valve 3, the fuel is supplied to the stacked battery 4.
Oxygen) is supplied to the MWl pond 4 by an air blower 5.

In this conventional method, if the storage pressure of the tough tank for storing the inert gas 2 is high, a tank or tank is required. ,
The drawback was an increase in volume.

The present invention directly connects a tank, a fuel pump, and an electromagnetic on-off valve to the fyI layer cell of the stationary liquid fuel cell in the above order, and further provides a power regulating valve in the bypass of the fuel pump. This method solves the drawbacks of the conventional method by changing the fuel pump motor drive voltage in conjunction with the load and changing the opening/closing interval of the electromagnetic on-off valve.

FIG. 2 is a system diagram showing the liquid fuel supply method according to the present invention. The liquid fuel stored in the balancing tank 1 has a fuel t[
Supplied by Borepro or the urn f- in the stacked battery 4
If i is sufficient, the electromagnetic on-off valve 3 is closed, so the liquid furnace material passes through the bypass, passes through the pressure regulating valve 7, and returns to the inlet side of the furnace material bowl/pro. The liquid furnace f1 on the outlet side of the professional is pressurized to the pressure set by the pressure horn adjustment valve 7. When a current is applied to the load 8, the current detector 9's Iha signal enters the control circuit 10, which is driven by the power of the stacked battery 4, and the output expressed as a function of the current is sent to the fuel pump 6 and the electromagnetic on-off valve. 3, the liquid fuel is supplied to the stack 7 and the pond 4. Control circuit 1o
In addition to the current detector 9, the input signal may be, for example, the voltage of the laminated IN battery 4 or the fuel concentration in the combustion chamber.By adopting the present invention, the capacity and volume can be reduced. , since it has the advantage of omitting the need to replace the evaporative gas cylinder. The commercial value of the 34 m pond in practical use is extremely large.
