Methods of producing and providing purified gas using an electrochemical cell |
摘要 |
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. |

1. A method of producing hydrogen gas meeting a predetermined threshold of purity, comprising:
separating a quantity of hydrogen gas from a hydrogen gas mixture by passing the 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, and wherein a current required to operate the electrochemical hydrogen pump increases as an amount of non-hydrogen from the hydrogen gas mixture is substantially prevented from passing through the membrane increases; purging the anode of the non-hydrogen in the hydrogen gas mixture that was prevented from passing through the membrane, wherein a controller controls timing of the purging based on a predetermined increase in the current required to operate the electrochemical hydrogen pump; collecting the hydrogen gas from the hydrogen gas mixture after it has been passed through the electrochemical hydrogen pump, wherein the collected hydrogen gas at least meets the predetermined threshold of purity; and producing at least one of a certificate, a guarantee, or a warranty that the collected hydrogen gas has a purity that is at least substantially equal to the predetermined threshold of purity. |
