The Ni catalyst was modified by adding Al through a solid-gas-solid reaction at a low temperature to produce an Ni-Al solid solution. This process allows for low-cost production of the modified catalyst. An activity test of the catalysts was carried out at 650 degrees C and 1 atm to simulate direct internal reforming of a molten carbonate fuel cell (MCFC). Experimental results showed consistent activity of the Al-modified catalyst, even after aging under severe conditions (900 degrees C) to simulate accelerated sintering. TEM data did not show any significant physical changes even after aging. Addition of Al appeared to have successfully prevented Ni from sintering without reducing its catalytic activity in reforming bio-ethanol. In addition, an Ni-Al/MgO catalyst, integrated into the anode of an MCFC, was successfully tested for over 2000 h without any significant performance degradation. (C) 2009 Professor T.
