Abstract: In certain embodiments, an apparatus includes an electrolyte membrane layer (EML), and includes a first electrode catalyst layer (ECL) and a first metallic gas diffusion layer (MGDL) positioned to a first side of the EML such that the first ECL is positioned between the first MGDL and the EML. The first MGDL includes a metal-containing layer and a coating of porous material disposed on a surface of the metal-containing layer of the first MGDL that faces the first ECL. The apparatus further includes a second ECL and a second MGDL positioned to the second side of the EML such that the second ECL is positioned between the second MGDL and the EML. The second MGDL includes a metal-containing layer and a coating of porous material disposed on a surface of the metal-containing layer of the second MGDL that faces the second ECL.

Abstract: In certain embodiments, a method includes forming a battery electrode on a substrate. Forming the battery electrode on the substrate includes depositing a first electrode active material layer on a first portion of a surface of the substrate and depositing, to form a current collector, a conductive material using a thin film deposition process on a surface of the first electrode active material layer. The conductive material is deposited over an edge of the first electrode active material layer and onto a second portion of the surface of the substrate, the second portion of the substrate being adjacent to the first portion of the substrate. The method includes removing the battery electrode from the substrate, the battery electrode including the first electrode active material layer and the current collector.
