BIOELECTRIC CHEMICAL BATTERY AND ELECTRODE FOR SAID BATTERY

摘要

Microbial activity in an aqueous medium is measured in a bioelectrochemical cell in which the working electrode comprises an electrically conductive carbon-bearing porous material; suitably a graphitized carbon felt or cloth. This enhances the BEC response by increasing the surface area and by absorbing microbes onto the surface; and the electrode material can also be used to preconcentrate the microbes prior to use as an electrode in the cell.
