Abstract
A positive electrode () for an air cell of the present invention includes: a catalyst layer () composed of a porous layer containing electrical conductive carbon (), a binder (), and a catalyst component (); and a fluid-tight gas-permeable layer () composed of a porous layer containing an electrical conductive carbon () and a binder (). The fluid-tight gas-permeable layer is stacked on the catalyst layer. This configuration can facilitate series connection of the air cells while preventing electrolysis solution from leaking out of a positive electrode. It is therefore possible to enhance the manufacturing efficiency and handleability of the air cells.
