DIRECT AMMONIA-FED SOLID OXIDE FUEL CELL AND METHODS FOR MAKING THE SAME

摘要

According to embodiments of the present disclosure, a solid oxide fuel cell includes a cathode, an anode, and a solid oxide electrolyte between the anode and the cathode. The solid oxide electrolyte includes a solid oxide, and the anode includes a porous scaffold. The porous scaffold includes a solid oxide having metal-based catalysts disposed on one or more surfaces of the porous scaffold. In embodiments, at least one ammonia decomposition layer is disposed proximate the surface of the porous scaffold and is configured to convert ammonia into hydrogen and nitrogen for subsequent feed of hydrogen to the anode. The ammonia decomposition layer also includes a metal decomposition catalyst.
