Claims20
A membrane-free water-splitting electrolyzer comprising:
- a power source configured to generate about 1.4 V to about 2.2 V;
- a rail reactor, wherein the rail reactor is operatively coupled to the power source, and wherein the rail reactor comprises a first and a second “U” shaped channel, each one having an open side along a length of the channel;
- and
- an electrocatalyst element, wherein the electrocatalyst element comprises a first and a second electrocatalyst,
- wherein the first electrocatalyst and the second electrocatalyst are electrically coupled to the power source,
- wherein only the first electrocatalyst is positioned within the first “U” shaped channel, and
- wherein only the second electrocatalyst is positioned within the second “U” shaped channel.
4 more elements
A system comprising:
- a plurality of rows, wherein each row of the plurality of rows comprises a plurality of membrane-free water-splitting electrolyzers, wherein each membrane-free water-splitting electrolyzer of the plurality of membrane-free water-splitting electrolyzers comprises:
- a rail reactor, wherein the rail reactor is operatively coupled to a power source configured to generate about 1.4 V to about 2.2 V, and wherein the rail reactor comprises a first “U” shaped channel and a second “U” shaped channel, each one having an open side along a length of the channel;
- and
