How does an electrolyzer work?
Electrolyzers are one way of extracting hydrogen from water. The process is basically the opposite of how a fuel cell works. An electrolyzer is made up of an anode, electrochemical cell and a cathode. Water and voltage is applied to the anode, which splits the water into hydrogen and oxygen. The hydrogen passes through the electrochemical cell to the cathode, while the oxygen travels around the cell. From there, the hydrogen and oxygen gases can be captured and stored. When electricity is required, the gases can be pulled from storage and routed through a fuel cell.
