Composition for forming a functional material layer, method for forming a functional material layer

Abstract

The exemplary embodiments provide: a composition for forming a functional material layer that can form a functional material layer of a constant quality for a long time, the composition for forming a functional material layer including a solution of a strong-acid functional material, to which a specific amount of a base is added so as not to corrode components of an ejection device. A method for forming a functional material layer includes the composition onto a substrate using ejection device. A method for manufacturing a fuel cell that has a first current-collecting layer, a first reaction layer, an electrolyte film, a second reaction layer, and a second current-collecting layer, includes forming at least one of the first and the second reaction layers by applying the composition for forming a functional material layer using the ejection device.

Description

technical field [0001] The present invention relates to a composition for forming a functional material layer ejected by an inkjet type discharge device (hereinafter referred to as "discharge device"), which is a non-corrosive composition characterized by not corroding the components of the discharge device. A composition for forming a functional material layer, a method for forming a functional material layer in which the composition is coated on a substrate by a spraying device, a method for manufacturing a fuel cell using the method, and a fuel cell with the composition Batteries are produced by fuel cells as power sources for electronic instruments and automobiles. Background technique [0002] Conventionally, there have been fuel cells composed of an electrolyte membrane, an electrode (anode) formed on one side of the electrolyte membrane, and an electrode (cathode) formed on the other side of the electrolyte membrane. For example, in a solid polymer electrolyte fuel c...

Problems solved by technology

[0012] However, since the hexachloroplatinum (IV) acid solution used as a material for forming the reaction layer is strongly acidic, when the reaction layer is formed by repeatedly ejecting such a solution with the ejection device, the part of the ejection device is gradually etched. The part of the nozzle head that makes the size and shape of the nozzle hole uneven

[0013] Therefore, it becomes difficult to apply a certain amount of the reaction layer forming material, and a new problem that the reaction layer in which the catalyst is uniformly dispersed cannot be formed.
