Title: Fuel cell
Inventor: OKADA HIDEO
IPC: H01M8/02
Filed: 1981-05-20
Abstract: PURPOSE:To make an electrolyte body to be hardly broken even when it is made thin by making long insulating fibers to hold the electrolyte of a fuel cell, which contains an ion-conducting salt soluble in acid such as an alkaline carbonate as an electrolyte, so as to make the said electrolyte body. CONSTITUTION:After a self-supporting matrix is formed by tangling long insulating fibers together, electrolyte is made to be held in the spaces of the above fibers so as to obtain an electrolyte body for a fuel cell. The above long insulating fibers should have length of above 100mum, and the ratio of the length (l) to the diameter (d) of the fibers preferably is above 10. By the use of long fibers having such length and such an l/d ratio, the above matrix is provided with sufficient self-supporting property, and has no possibilities of being broken during the use. Here, much more higher mechanical intensity can be given to the above matrix by sintering long fibers after they are tangled together and formed into a given shape. This can be achieved by making long alumina fibers in contact with a powdery or liquid lithium salt, and converting them into lithium aluminate fibers by thermal treatment. Since an electrolyte body containing thus prepared lithium aluminate fibers as a matrix becomes in close contact with an electrode, high output of a fuel cell can be realized.
