International audienceStainless steel is gaining increasing interest as an anodic material in bioelectrochemical systems and beginning to challenge the more conventional carbon-based materials. Here, microbial bioanodes designed under optimal conditions on carbon cloths gave high current densities, 33.5 + 4.5 A m−2 at −0.2 V/SCE, which were largely outstripped by the current densities of 60 to 80 A m−2 at the same potential and more than 100 A m−2 at 0.0 V/SCE provided by using stainless steel foams
