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.
