内容摘要：Electrodes are extremely important interfaces in anyelectrical devices. The performance of such devices can be improved by order ofmagnitudes as recently shown by use of electrospun scaffolds as electrodes inmicrobial fuel cells. The use of porous scaffolds as electrodes has stimulateda new trend in the field of microbial fuel cells and a rocket-like increase inthe performance of microbial fuel cells. The major challenge for polymer-basedporous scaffolds as electrodes is electrical conductivity While polyaniline andmostly carbon do not display sufficient electrical conductivity for a reallyhigh performance, really highly porous scaffolds are still a major challenge.We overcome this problem by a metallization of porous polymer scaffolds whichshowed extremely good conductivity. The challenge here was to achievehomogenous metallization all over the porous scaffolds which we did by suitablechemical conditions. Another big question mark was the use of metals likecopper and silver as electrode materials in microbial fuels where livingmicrobes are the major player. On the other hand, silver and copper arewell-known antimicrobial materials. However, we could clearly show that copperand silver can be used as electrode materials in microbial fuel cells.
