Abstract

PURPOSE:To prevent deterioration of an anode by providing such construction as that an anolyte chamber is filled with anolyte even when an anolyte pump is stopped. CONSTITUTION:While an anolyte pump 5 is in operation, anolyte 7 stored in an anolyte tank 8 passes through the anolyte pump 5 and a valve 6 for being supplied to the anolyte chamber 3 of a liquid fuel cell. The valve 6 is only required to check a back flow of anolyte. The anolyte which contains the gas formed due to an electrochemical reaction at an anode 1 returns again to the anolyte tank 8 so as to continue said circulation so long as the anolyte pump is in operation. when the anolyte pump 5 stops, the anolyte in the anolyte chamber 3 stays as it is in the anolyte chamber 3 due to the action of the valve 6.

があった。BACKGROUND OF THE INVENTION Conventionally, in this type of liquid fuel cell, it has been common to operate an anolite pump and an anolite tank by installing them at the bottom of the liquid fuel cell main body.0 Problems to be Solved by the Invention However, In this method, the anolite chamber is filled with anolyte while the anode is being supplied to the anode by the anolite pump, but when the anolite pump is stopped, the anorite chamber is filled with air due to the diffusion of air from the air electrode. However, the methanol or hydrazine remaining at the anode and oxygen in the air cause a direct oxidation reaction under the anode catalyst, resulting in deterioration of the 72 node characteristics.
