Abstract
An electrochemical cell structure has an electrical current-carrying structure which, at least in part, underlies an electrochemical reaction layer. The cell comprises an ion exchange membrane with a catalyst layer on each side thereof. The ion exchange membrane may comprise, for example, a proton exchange membrane. Some embodiments of the invention provide electrochemical cell layers which have a plurality of individual unit cells formed on a sheet of ion exchange membrane material.
