摘要： An object of the present invention is to provide a catalyst-coated membrane suitable for achieving a polymer electrolyte fuel cell that sufficiently prevents a decrease in the initial characteristics and also exhibits sufficient cell performance for a long period of time and has excellent durability. In at least the cathode catalyst layer, the ratio (WP/WCat-C) of the weight of the polymer electrolyte (WP) to the weight of the catalyst-carrying carbon (WCat-C) is decreased from an innermost layer positioned closest to the polymer electrolyte membrane toward an outermost layer positioned farthest from the polymer electrolyte membrane. The ratio (WP/WCat-C) in the innermost layer is 0.8 to 3.0, and the ratio (WP/WCat-C) in the outermost layer is 0.2 to 0.6.

摘要： Ceramic-metal composite bodies and a process for the production thereof are disclosed. The ceramic-metal composite body includes a metallic member and a ceramic member which are integrally joined together by fitting a projection formed on the ceramic member to a recess formed in the metallic member. The projection of the ceramic member is fitted and joined into the recess of the metallic member in a vessel of which the inside is kept at an atmosphere having a pressure lower than an atmospheric pressure. The pressure of air remaining in a space left between the recess and the fitted projection is lower than that of the air in the space when the projection is fitted into the recess in the atmospheric pressure. An apparatus for fitting and joining the projection of the ceramic member to the recess of the metallic member is also disclosed, which includes a pressure-reducible vessel which is provided with a space for receiving at least the projection of the ceramic member and the recess of the metallic member, a sealing structure including O-rings or the like, a pipe opening for exhausting air inside the vessel, and a movable push rod for pressing and fitting the projection of the ceramic member into the recess of the metallic member.
