Platinum sensibility to impurities in hydrogen fuel cells remains one of the major issues to be solved in order to achieve a large scale commercialization of fuel cells. One way to do this can be the use of enzymes as catalysts in fuel cell internal processes. Moreover, enzymes and other biocatalysts can be used to develop a wide range of biofuel cells that can use fuels such as sugars, alcohols ...[1,2]. In the present work, several biocatalyst-electrode material systems were electrochemically studied by linear voltammetry with the aim to find new alternatives for both cathodic and anodic reactions in biofuel cells by exploiting the direct electron transfer capability of enzymes. The employed biocatalysts were laccase, hydrogenase, glucose oxidase and hemin. They were coupled with titanium, stainless steel, glassy carbon, and graphite electrodes. Results showed that the electrocatalysis based on direct electron transfer is possible on stainless steel and titanium, and that hemin is a promising electrocatalyst for oxygen reduction
