An electrolyzer cell () for the electrolysis of water comprises a cathode () of generally tubular configuration within which is disposed an anode () separated from the cathode () by a separation membrane () of generally tubular configuration which divides the electrolyte chamber () into an anode sub-chamberand a cathode sub-chamber (). An electrolyzer apparatus () includes an array () of individual cells ()across each of which an electric potential is imposed by a DC generator () via electrical leads (). Hydrogen gas generated within cells () from electrolyte () is removed via hydrogen gas take-off lines () and hydrogen manifold line (). By-product oxygen is removed from cells () by oxygen gas take-off lines () and oxygen manifold line (). The electrolyzer apparatus () may be configured to operate either batchwise or in a continuous electrolyterecycle operation to produce high purity hydrogen at high pressure, e.g., up to about (10,000) psig, without need for gas compressors to compress product hydrogen.

Electrolyzer apparatus and method for hydrogen and oxygen production

An apparatus and method for inerting the gas present in the ullage region of a storage tank for combustible liquids, e.g., a fuel tank containing a hydrocarbon liquid fuel, utilizes a molecular sieve zone (, beds) which either (a) selectively adsorbs oxygen from the ullage gas to provide an oxygen-depleted return ullage gas, or (b) selectively adsorbs nitrogen from the ullage gas, which nitrogen is desorbed and conveyed by a purge gas to provide a nitrogen-enriched gas. The return ullage gas or the nitrogen-enriched gas is flowed to the ullage region () in quantity sufficient to render the overall composition of gas in the ullage region () non-combustible and non-explosive. The apparatus may include a compressor () or a vacuum pump to flow the ullage gas through the system, and a valving arrangement () is used to control the flow of gases. Operation may be intermittent or continuous and may comprise pressure-swing adsorption/desorption to place one of molecular sieve beds () on-line to adsorb oxygen or nitrogen from the ullage gas, while the other of molecular sieve beds () is off-line being regenerated.
