Abstract

In accordance with one embodiment, a method of producing hydrogen gas meeting a predetermined threshold of purity may include transferring a quantity of a hydrogen gas mixture through an electrochemical hydrogen pump, wherein the electrochemical hydrogen pump includes an anode, a cathode, and an electrolyte membrane located between the anode and the cathode; separating a quantity of hydrogen gas from the hydrogen gas mixture by transferring the hydrogen gas from the anode, through the electrolyte membrane, to the cathode; collecting the hydrogen gas from the cathode, wherein the collected hydrogen gas at least meets the predetermined threshold of purity; and producing a certificate that the collected hydrogen gas has a purity that is at least substantially equal to the predetermined threshold of purity.

Description

[0001] This patent application claims priority under 35 U.S.C. §120 to U.S. Provisional Application No. 61 / 840,843, filed June 28, 2013, which is hereby incorporated by reference in its entirety. technical field [0002] Embodiments of the present invention relate to electrochemical cells, and more particularly, to methods of utilizing electrochemical cells for gas purification, monitoring, and / or for providing purified gas. Background technique [0003] Hydrogen has emerged as a viable alternative to traditional energy sources such as fossil fuels for a range of technologies including (for example) transportation vehicles, portable power sources and stationary power production. The successful commercialization of hydrogen as an energy carrier and the long-term sustainability of the "hydrogen economy" may depend in part on the efficiency and cost of hydrogen manipulation and management systems (e.g., EHC) and hydrogen distribution systems (e.g., distribution stations) benefi...
