    Abstract: Method and system for electrochemically compressing hydrogen. In one embodiment, the system includes a membrane electrode assembly (MEA) that includes a polymer electrolyte membrane (PEM), an anode, and a cathode. First and second gas diffusion media are positioned adjacent the cathode and anode, respectively. A humidifying membrane is positioned next to the second gas diffusion medium on a side opposite the anode. A water supply is connected to the humidifying membrane, and a hydrogen gas supply is connected to the second gas diffusion medium. A hydrogen gas collector including a back pressure regulator is connected to the first gas diffusion medium. Separators, positioned on opposite sides of the MEA, are connected to a power source.

  • Patent number: 11846032
    Abstract: Catalyst systems employing inexpensive and readily-available protic co-catalysts to increase a proton reduction rate in a hydrogen evolution reaction (HER) are described herein. The protic co-catalysts function to increase the rate without being consumed in the process of water splitting to hydrogen and oxygen. They may simultaneously serve to stabilize the pH of the water and be the electrolyte to carry the current for the electrolytic splitting of water. The protic co-catalysts also decrease the overpotential energy requirement for the process of water splitting. These protic co-catalysts can be used with both heterogeneous and homogenous catalysts, as well as assist photocatalysis and other processes for the reduction of protons.
