          Abstract

          RESUMO Os incentivos às políticas energéticas e as atuais exigências ambientais motivam a busca por fontes de energia alternativa, como o gás hidrogênio. Este trabalho tem como objetivo a produção do gás hidrogênio via eletrólise do ácido fórmico, utilizando eletrodos de aço carbono 1008 e ferro Armco. Os ensaios foram feitos mediante planejamento experimental, e empregaram-se as técnicas de microscopia óptica, polarização potenciodinâmica catódica, potencial de circuito aberto e cronoamperometria. Os resultados mostraram que o tratamento da superfície dos eletrodos com lixa de carbeto silício (SiC) #320 é eficiente quando comparada aos outros tratamentos testados, para o desprendimento de H2. O ferro Armco, apresentou maior produção de hidrogênio, em média 70% a mais quando comparado com a platina em ambos os meios estudados, entretanto sua vida útil é menor.

          ABSTRACT Incentives for energy policies and current environmental requirements motivate the search for alternative energy sources such as hydrogen gas. This paper aims at the production of hydrogen gas via electrolysis of formic acid using electrodes of 1008 carbon steel and Armco iron. Samples were done by experimental design, and employed the techniques of optical microscopy, cathodic potentiodynamic polarization, open circuit potential and chronoamperometry. The results showed that the surface treatment of the electrodes with #320 grit SiC abrasive paper is effective when compared to the other treatments tested for the evolution of H2. The Armco iron, showed higher hydrogen production, on average 70% increased when compared with platinum in both studied media, however its lifetime is shorter.
