  • Systems and methods of production of hydrogen containing compounds using products of fuel cells
    Patent number: 10766770
    Abstract: Disclosed herein are methods and systems for the production of hydrogen-containing compounds, such as ammonia and urea from a product stream of a fuel cell unit. The production of ammonia and optionally urea can also include a net power production. Alternatively, the hydrogen stream from the fuel cell unit can be directed to the production of synthetic hydrocarbons liquids.
