In one embodiment the high surface area electrode has an electrode backing and villiated extensions attached to the backing. In one embodiment the villiated extensions and/or electrode backing are made of an electroconductive material such as, for example, graphite or graphite fibers. In one embodi­ ment the electrode is an anode and the electrode backing is in the form of a mesh or woven structure. The electrodes offer superior removal of chemical oxygen demand (COD) and are thus useful in the remediation of wastewaters. The invention also provides mi­ crobial fuel cells that utilize the electrodes of the invention. In one embodiment the microbial fuel cells utilize an oxygen barrier and do not utilize a cation or anion or proton exchange membrane.
