Abstract

An electrolytic device (20) comprising a structure (22) having a first surface (24) with a first surface area, a thickness region (29) and a plurality of openings (30) in the thickness region. The plurality of openings (30) is defined by a plurality of inner surfaces (34) that together have an inner surface area. The plurality of inner surfaces comprise silver. A metal-bearing material (40) other than silver is interspersed throughout at least some of the plurality of openings.
