Abstract
Recently researchers have focused to enhance the electrocatalytic activity of the biosystems, increasing the energy generation and electronic conductivity into the biofilms. Enzymes immobilized onto the surface of electrodes in biological fuel cells has been extensively reported. A biofuel cell provides a means to obtain clean, renewable energy and have great potential to be used as alternative energy source for low power devices. Some important development to obtain the maximum energy from the fuels are the focus of this presentation. To enhance the power density of enzymatic biofuel cell (EBFC) it is necessary to deep oxidize the fuels, that is to say that all the electrons from the fuel must be removed. There are two main routes to obtain this (i) immobilization of a group of target enzymes to perform a cascade in order to maximize the fuel oxidation; (ii) development of hybrid biofilms employing a mixture of organic catalyst or noble metals nanoparticles with an enzyme able to break C-C bonds. We will present recent configuration to complete oxidize ethanol (ET) and ethylene glycol (EG) into CO2.
