Title: Electrochemical gas purifier

Abstract: The electrochemical gas purifier system consists of a cell module with accessory components mounted in a single framework. The module consists of a number of single cells each capable of purifying and ultimately producing hydrogen gas at pressures exceeding 2000 psi. The process comprises introducing a contaminated hydrogen stream to a cell comprising an anode and a cathode with an electrolyte membrane disposed therebetween. The hydrogen is oxidized on the anode to protons which electrochemically migrate across the membrane to the cathode where they recombine with electrons which have passed through an external power source. The contaminants exit the anode side of the cell while the purified hydrogen exits the cathode side of the cell.
