Abstract

See full text

Provided are methods and systems for combining hydrogen supply and fuel cell processes for increased efficiency of electricity generation. The method may include decomposing methane to produce at least hydrogen, introducing at least a portion of the hydrogen to a fuel cell to generate at least electricity and heat, and capturing at least a portion of the heat from the fuel cell to reduce an electricity requirement for the methane decomposition. The system may include a methane preheater, a reaction system, a hydrogen storage system, a hydrogen fuel cell, and a heat recovery unit. The reaction system may comprise one or more reaction chambers containing a liquid base fluid, carrier droplets and a catalyst, wherein the reaction system is configured to decompose methane. The heat recovery unit may be configured to supply waste heat from the hydrogen fuel cell to the methane preheater.
