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. |
