摘要： This disclosure provides systems, methods, and apparatus related to a porous transport layer for use in an electrolyzer. In one aspect, a method includes providing a porous transport layer this is to be a component in an electrolyzer cell. Features are created in a first surface of the porous transport layer. The features serve to increase a surface area of the first surface of the porous transport layer.

摘要： An electrochemical method for producing calcium hydroxide includes dissolving a calcium precursor in a first solution in contact with a first electrode to produce Ca2+ ions, transporting the Ca2+ ions across a first membrane from the first solution into a second solution using a first electrochemical potential, producing hydroxide ions at a second electrode, transporting the hydroxide ions across a second membrane into the second solution using a second electrochemical potential, and precipitating calcium hydroxide from the second solution.
