で採られている従来の系統図である。Conventional technology Conventionally, in a stationary liquid fuel cell, an electrolytic solution is supplied to an electrolytic solution chamber, an electrolytic solution or a mixed solution of electrolytic solution and fuel (hereinafter referred to as "anolyte") is supplied to a fuel chamber, and the electrolytic solution is kept stationary, and only fuel is supplied. This is used to replenish the fuel chamber, but unlike conventional liquid fuel cells, it does not have a system for circulating the anolite, so it is not possible to mix fuel with the anolite and supply it into the cell; instead, only liquid fuel is used. A method is adopted in which fuel is supplied under pressure to the fuel chamber. FIG. 1 is a conventional system diagram employed in the operation of a stationary liquid fuel cell.

問題を有している。Problems to be Solved by the Invention When starting the stacked battery 3, if the electrolytic solution or anolite is first supplied to the fuel chamber 12 and kept stationary, the electrolytic solution or anolite will be absorbed into the fuel filter 14, and the fuel replenishment will continue over time. It penetrates into the passageway 13. When refueling the refueling passage 13 in such a state, the electrolyte has permeated into the refueling passage 13, so that the liquid short-circuit current between each unit cell increases, and the fuel in each unit cell increases. This poses a problem in that fuel cannot be uniformly supplied to the chamber 12.
