300°C Proton-Exchange Membrane for Low-Pressure Electrolytic Ammonia Synthesis
The two North Dakota universities and Proton OnSite are developing a 300°C-capable polymer–inorganic composite (PIC) proton exchange membrane for low-pressure (15-psi) ammonia synthesis. The PIC membrane comprises an inorganic proton conductor strategically composited within a high-temperature polymer to enable a proton conductivity of 10-2 siemens/centimeter at 300°C. Integrated with appropriate low-cost anode and cathode catalysts in a membrane–electrode assembly, the gas-impermeable PIC membrane is projected to enable ammonia production at a total energy input of about 6400 kilowatt-hours/ton (kWh/ton), versus about 8500 kWh/ton for state-of-the-art Haber Bosch-based ammonia production. The PIC membrane will also have application in high-temperature water electrolysis…

Low-Pressure Electrolytic Ammonia Synthesis Via High-Temperature Polymer-Based Proton Exchange Membrane
The University of North Dakota Energy and Environmental Research Center (EERC) and North Dakota State University (NDSU) have developed a low-pressure electrolytic ammonia (LPEA) production process. The LPEA process uses an electrochemical cell based on an innovative polymer–inorganic composite (PIC) high-temperature (300°C) gas-impermeable proton-exchange membrane conceptualized and partially developed by EERC and NDSU. Because of its operability at ambient pressure and quick start-up capability (versus traditional high-pressure Haber Bosch-based plants), the LPEA process offers compatibility with smaller-scale plants and intermittent operation, and a cost-effective means of monetizing (and storing) renewable energy as ammonia. EERC, NDSU, and Proton OnSite are embarking…
