    Abstract: An article comprising a first gas distribution layer (100), a first gas dispersion layer (200), or a first electrode layer, having first and second opposed major surfaces and a first adhesive layer having first and second opposed major surfaces, wherein the second major surface (102) of the first gas distribution layer (100), the second major surface (202) of the first gas dispersion layer (200), or the first major surface of the first electrode layer, as applicable, has a central area, wherein the first major surface of the first adhesive layer contacts at least the central area of the second major surface of the first gas distribution layer, the second major surface of the first gas dispersion layer, or the first major surface of the first electrode layer, as applicable, and wherein the first adhesive layer comprises a porous network of first adhesive including a continuous pore network extending between the first and second major surfaces of the first adhesive layer. The articles described herein are useful, for example, in membrane electrode assemblies, unitized electrode assemblies, and electrochemical devices (e.g., fuel cells, redox flow batteries, and electrolyzers).
