Catalysts and Performances for Direct Methanol Low-Temperature ( 300 to 600   C ) Solid Oxide Fuel Cells

Abstract: A novel anode catalyst, C-MO-SDC ͑C = activated carbon/carbon black, M = Cu, Ni, Co, SDC = Ce 0.9 Sm 0.1 O 1.95 ͒ was synthesized by employing a citrate/nitrate combustion technique. Carbon materials, e.g., activated carbon and carbon black were first used to improve the solid oxide fuel cell ͑SOFC͒ anode properties, especially to improve the microstructure and to enhance the anode conductivity and catalyst function for directly operating methanol as the fuel. The resulting anode catalyst C-MO-SDC materials us… Show more

“…For small-scale portable applications, it is meaningful to directly use methanol in SOFCs because methanol has low content of impurities which can poison the anode [11,12]. Meanwhile, pyrolysis and catalytic decomposition of methanol can be readily achieved at typical SOFC anodic conditions [13], favoring subsequent electrochemical oxidation of the products of these reactions, which are mainly CO and H 2 [14,15].…”

“…Firstly, oxygen content in CH 3 OH can thermodynamically promote to oxidize the carbon which was deposited on metal active sites inhibiting catalytic reaction. [7][8][9][10] Secondly, methanol can be easily reformed to CO and H 2 at low temperature. Portability of methanol fuel was key point to expand range of application.…”

“…Among inexpensive metal group, copper is expected to be applicable as an anode material for methanol since it is widely used as the catalyst for methanol decomposition. [26][27][28] Although Cu is active for methanol decomposition, it is not good catalyst for the electrochemical oxidation of H 2 and CO. The copper simply acted as an electrical conducting path in SOFC.…”

“…O óxido de cério é de grande importância por suas propriedades ópticas, alta estabilidade térmica, condutividade elétrica e difusividade, e a capacidade para armazenar e liberar oxigénio. Por estas propriedades, o CeO 2 pode ser utilizado como abrasivo [2], pigmento [3], material de catálise [4], eletrólito sólido de condução de íons oxigênio [5], e sensor de oxigênio [6]. Nos últimos anos foram realizadas algumas tentativas para a preparação de óxido de cério dopado com íons terras raras por várias técnicas, tais como pirólise [7], síntese solvotérmica [8,9], síntese sonoquímica [10], coprecipitação de dois estágios [11,12], processo sol-gel [13,14], reações de estado sólido [15], irradiação por micro-ondas [16], etc.…”
