Abstract

A polymer electrolyte electrochemical device includes an anode current collector (1), a membrane electrode assembly (2) with anode and cathode gas backings (3, 4), and a cathode current collector (5), wherein the membrane electrode assembly is sealed and attached at least to the anode current collector by adhesive elements, thereby creating an anode gas chamber, and optionally attached to the cathode current collector by adhesive elements, the adhesive elements being electrically conducting or electrically non-conducting. The invention also relates to polymer electrolyte electrochemical device components adapted for use in a single cell electrochemical device and a series arrangement electrochemical device.
