Researchers at Penn State University have found a way to replace the platinum-catalyzed carbon cloth cathodes in their hydrogen-generating microbial electrolysis cells (MEC) (earlier post) with high surface area stainless steel brush cathodes without losing efficiency. Stainless steel brush cathodes…
