In Situ Water Electrolyzer Stack for an Electrobioreactor

In Situ Water Electrolyzer Stack for an Electrobioreactor

Hydrogen-oxidizing bacteria provide a sustainable solution for microbial protein production. Renewable electricity can be used for in situ water electrolysis in an electrobioreactor. The use of cultivation medium as the electrolyte enhances the hydrogen dissolution to the medium. This paper proposes...
