を用いていた。2. Description of the Related Art Conventionally, as a method for keeping the amount of anolite constant in a liquid fuel cell, a method has been used in which an anolite plate curve detection element is used to control the anolyte liquid level in an anorite tank above a certain level.

下の場会には、アノライトタンクに水が供給される。Problems to be Solved by the Invention In general, operation of a liquid fuel cell begins with supplying anode to the anode by an anode pump and air to the cathode by a blower. At this point, the liquid fuel cell does not supply electricity, and the auxiliary equipment and control devices (anolite pump, blower 5 fuel and water supply device, heater, etc.) are powered by an auxiliary power source such as a lead acid pond. be done. Then, when the liquid level in the anorite tank is below a certain level, water is supplied to the anorite tank.
液体燃料電池の温度が一定値以上となると、発電を開始
し、外部に電力を供給し始める。When the temperature of the liquid fuel cell reaches a certain value or higher, it starts generating electricity and begins supplying power to the outside.

アノライトを循環してもアノライトタンクの液面の高さ
が異なる。When the liquid fuel cell is discharged T, a reaction gas is generated at the anode and a portion of this is accumulated in the anorite chamber. For this reason, even if the same amount of anolite is circulated, the height of the liquid level in the anolyte tank will be different between a site that supplies external power and a site that does not.

せがある。If you set a liquid level sensor on the liquid curved island during discharge when power is being supplied, the liquid level sensor will work as the liquid level will be lower than this at the beginning of operation without power supply. Water will be supplied. When discharge starts under such conditions (power), the reaction gas accumulates in the anolite chamber. Therefore, the liquid level becomes high, and if the volume of the anolyte tank is small, the anolyte is There is an opportunity to overflow.

ようＥこしたものである。Means for Solving the Problems In order to achieve the above-mentioned object, the present invention provides that the liquid fuel cell starts generating electricity, and that the generated gas accumulates in the anorite chamber and reaches the equilibrium level within a certain period of time. The liquid level in the anolyte tank is controlled in a low state, and after a certain period of time, the liquid level in the anolyte tank is controlled in a high state.
