Abstract
A method for enhancing a microbial environment for a fuel cell can include the initial step of oxidizing the outer surface of the fuel cell anode to establishing reactive chemical functional groups. The anode surface can be oxidized by washing the anode with a solution of 4-carboxybenzene diazonium tetrafluoroborate, followed by washing with acetone, methanol and water. Once the anode surface has been oxidized, the methods can include the step of binding a surface graft matrix to the reactive chemical functional groups (the activated carboxyl groups on the anode surface). EDAC and sulfo-NHS can be used as a surface graft matrix, to bind to the activated carboxyl groups. A biological substance, such as a biological agent or biomolecule, can be chemically attached to the outer terminal reactive groups of the surface graft matrix. The result is a microbial fuel cell with increased power generation and durability properties.
