PURPOSE:To enable a performance withstanding even a heavy load discharge, and a discharge for long time by introducing oxygen in air to a cell via a hollow yarn having a fine hole in a wall surface. CONSTITUTION:An air pole catalyser layer 5 is provided on a water repellent membrane 6 composed of a micro-porous film, a hollow yarn 7 having a fine hole and a hole 10 to which the hollow yarn 7 is inserted via a dispersing paper 8 are provided in a wall surface in the back surface, and a positive electrode is formed with a peripheral part of a positive electrode current collecting body 9 fixed by adhesive. A negative electrode is formed by providing a negative electrode active material layer to the back surface of a negative electrode current collecting body 1 with the peripheral part remained. In this case, the hollow yarn 7 is made of polyethylen or polypropylene, oxygen in air is taken in via the hollow yarn 7, and the air enters well in the inside of a cell. This enables the touching area of the catalyser layer 5 and the air to be increased, a contamination of water vapour and carbon dioxide etc. into a cell to be prevented, a deterioration of a cell performance and a leakage of liquid to be decreased sharply, and a heavy load discharge to be made. |
