“…Then, 100 psi of pressure was applied to the green sheet anode with an air cylinder for 100 h, and the thickness variation of the electrode was measured using the micro thickness gauge attached to the equipment. Creep strains of the as-prepared NieAleCr alloy samples were evaluated from the following creep ratio equation [7]:…”

“…Following Hippsley's suggestion [12], Cr addition up to 8 wt.% into the Ni 3 Al system has a significant effect on preventing the crackgrowth phenomenon by improving the tensile strength of the modified material. However, the high creep strain of the NieNi 3 Ale Cr system is discussed without consideration for the phase of the ternary system [6,7]. Therefore, more studies regarding the application of the NieAleCr system applied in MCFCs are necessary.…”

“…It was prepared through a procedure involving tape casting, drying, and calcination of a slurry mixture of solvent (water), binder (methyl cellulose #1500; Junsei Chemical Co., Japan), plasticizer (glycerol; Junsei Chemical Co., Japan), defoamer (SN-154; San Nopco, Korea), deflocculant (cerasperse-5468; San Nopco, Korea), and Ni powder (INCO #255; particle size: 3 m), as reported previously [3]. The coating solution was prepared by mixing ceria sol (Alfa; 20% colloidal dispersion in H 2 O) and ethanol (99.9%, Hayman) in a 1:2 weight ratio.…”

“…It is well established that even low-partsper-million concentrations of sulfur compounds in fuel gases are detrimental to MCFCs. The principal sulfur compound that causes adverse effects on cell performance is H 2 S. At anodic potentials, nickel anodes react with H 2 S to form nickel sulfide, which can block active electrochemical reaction sites [1]: 3 2− → H 2 O + CO 2 + S 2− (1) * Corresponding author. Tel.…”

Resumo: Embora não seja tecnologia recente, as células a combustível ou Fuel Cells (FC) continuam recebendo grande atenção, pois são consideradas como "fontes de energia do futuro" devido a características como alto rendimento energético e baixa emissão de poluentes, permitindo a extensão o tempo de vida das reservas fósseis e contribuindo para a melhoria da qualidade de vida. Atualmente, as pesquisas estão direcionadas, principalmente, ao desenvolvimento de FC para aplicações em sistemas móveis e portáteis. De todas as tecnologias existentes, a mais promissora para essa finalidade é a célula a combustível de eletrólito polimérico, conhecida como PEMFC (Polymer Electrolyte Fuel Cell) cuja pesquisa encontra-se focada, principalmente, no desenvolvimento de membranas poliméricas, com o objetivo de reduzir os custos de produção. Este trabalho será focado nos aspectos físico-químicos do desenvolvimento de membranas poliméricas. Serão discutidos aspectos estruturais do Nafion ® relacionado-os as seguintes propriedades físico-químicas: fluxo eletrosmótico, permeabilidade gasosa, transporte de água através da membrana, estabilidade química e térmica. Toda a discussão será realizada para polímeros perfluorados, utilizando o Nafion ® como modelo representante dessa classe de polímeros. Palavras-chave: Célula a combustível, membrana polimérica, Nafion ® . Physicochemical Properties Related to the Development of Nafion ® Membranes for Application in Fuel CellsAbstract: Fuel Cells (FC) continue to receive growing attention, in spite of not being a new technology, for they are considered as the "energy source of the future" owing to characteristics such as high energetic yield and low emission of pollutants. FC technology may lead to a reduction in the negative impact from energy sources on the enviroment, thus improving the quality of life and extending the lifetime of fossil combustible reserves. The mainstream of research in FC is now directed at mobile, portable systems, for which the most promising technology is the Polymer Electrolyte Fuel Cells, also known as PEMFC (Polymer Electrolyte Fuel Cell). Research in this topic focuses on the development of polymer membranes whose target is to reduce its production costs. In this work we shall focus on physicochemical aspects related to development of polymeric membranes. A discussion on structural aspects of Nafion ® will be carried, which will be related to the following physicochemical properties: electrosmotic flux, gaseous permeability, water transport through polimeric membrane, chemical and thermal stabilities. All the discussion was made using Nafion ® as model of perfluorated polymers.
