PURPOSE:To obtain a liquid fuel cell of excellent cell characteristic, by using an ion exchange film of excellent ion permeability further with excellent stopping power for a liquid molecule as the partition film. CONSTITUTION:A selectively permeable film is constituted such that fine particles 3 physically and chemically stable for processed liquid are held in the inside of at least an applicable hole 2 of a porous organic high molecular film 1 to provide fine hole size permeably controlled for only a gas state or liquid low molecular material or ion in said liquid. Holding of the particles 3 decreases virtual size of the hole 2 to improve selective permeability. A fine particle chemically or physically stable for a cell electrolyte, for instance, sulfuric acid and phosphoric acid or the like is only required as the particle held to a porous ion exchange film. Under a condition operated as a fuel cell, the ion exchange film as the partition film contains a cell electrolyte. Here an acid electrolyte of, for instance, sulfuric acid, phosphoric acid, etc. and alkaline electrolyte of potassium hydroxide, sodium hydroxide, etc. are used as the electrolyte. |
