Abstract
A method for operating an electrolysis cell at a range of pressures and current densities, the cell having an ultrathin composite membrane, preferably comprising an expanded polytetrafluoroethylene base material impregnated with a hydrogen conducting ionomer. The resulting membrane is unexpectedly durable and efficient when used in an electrolysis cell operating at high membrane pressure differentials, thereby allowing greater cell current densities and efficiency.
