Abstract
According to embodiments of the present disclosure, a method of producing hydrogen in a fuel cell includes passing ammonia under pressure to an anode of the fuel cell, where the ammonia is decomposed into nitrogen gas and protons. The fuel cell comprises a cathode, the anode, and a proton-conducting electrolyte between the anode and the cathode. The anode includes an ammonia decomposition catalyst. The method further includes passing the purging the nitrogen from the anode, passing the protons through the proton-conducting electrolyte to the cathode, and passing the electrons from the anode to the cathode, wherein the protons and the electrons react to produce substantially pure hydrogen gas under pressure.
