ELECTRODE, MEMBRANE ELECTRODE ASSEMBLY, ELECTROCHEMICAL CELL, STACK, AND ELECTROLYZER

Abstract

An electrode according to an embodiment includes a support comprising metal fibers or metal particles, the support comprising a first surface and a second surface located opposite the first surface and a catalyst layer provided on the metal fibers or the metal particles on the first surface side of the support. An average fiber diameter of the metal fibers and an average primary diameter of the metal particles are denoted as D. A direction from the first surface of the support to the second surface of the support is a thickness direction of the support. The catalyst layer is provided at from the first surface to a position at a minimum depth of 3×D or more and a position at a maximum depth of 10×D or less.
