Abstract
A membrane for use with an electrochemical apparatus is provided. The electrochemical apparatus may include a fuel cell or electrolyzer, for example, an electrolyzer adapted to produce hydrogen. The membrane comprises a fabric made from a synthetic fiber such as nylon where the nylon, in an exemplary embodiment, is woven into ripstop nylon fabric. The electrochemical apparatus is constructed with frames comprising high-density polyethylene (HDPE) which provide support and structure to the membranes as well as to internal electrodes. A method of making an electrochemical apparatus, such as an electrolyzer, containing a membrane comprising ripstop nylon is also disclosed, as is a method for producing hydrogen gas with an electrolyzer containing a membrane comprising ripstop nylon.
