Fuel cell
专利汇可以提供Fuel cell专利检索，专利查询，专利分析的服务。并且PURPOSE:To obtain a fuel cell which contains electrolyte having a high temperature and a high concentration, and which has a long life by using as a sealing agent either a fluorine-rubber-system adhesive or a mixture consisting of said adhesive and a specific extending agent. CONSTITUTION:A fluorine-system rubber adhesive is used as a sealing agent applied to the corners and the peripheries of a stacked body consisting of unit cells and interconnectors. In using such an adhesive, a solution usually containing 30- 60wt% of a fluorine-rubber-system adhesive is applied to joined parts such as the corners and the peripheries of the stacked body, and the adhesive coats are changed into rubber-like form by vaporizing the solvent at room temperature or under a heated condition. When it is desired that the adhesive is applied in a thick layer, the adhesive is applied several times, the solvent is evaporated every time of the application of the adhesive, and such a process is carried out repeatedly. As a fluorine resin, polyfluoroethylene, polyfluoroethylene propylene, polyphlorofluoroethylene or the like is employed. As an extending electrolyte resistance and, especially, a high phosphoric-acid resistance is desired.，下面是Fuel cell专利的具体信息内容。
