Abstract
In the past years, steam methane reforming (SMR) is a standard solution for the hydrogen production from hydrocarbon fuels for the development of commercial units of intermediate temperature solid oxide fuel cells (IT-SOFCs) systems. However, feeding methane as fuels can induce carbon deposition which would deteriorate the microstructure of the anode and endanger the lifetime of cells. As a result, ammonia becomes the alternative fuels for SOFCs since no residuals will be deposited onto the anode surface. The only concern of the ammonia fuels is the tentative formation of nickel-nitrogen (Ni3N) compound on the anode surface from recent reports. In this paper, Heusler alloy was deposited on the porous anode by sputtering to disassociate ammonia as the hydrogen sources and detour the possible pathways for Ni3N formation. The planar SOFCs is composed of anode-supported Ni-Sm0.2Ce0.8O2-δ (Ni-SDC) and the cathode of La0.6Sr0.4Co0.2Fe0.8O3-δ (LSCF) with the operation temperature of 650°C. The micro-scale material properties and the stability of crystalline of Heusler-SDC single cells will be examined for 10 hours tests.
