acid–alkaline hybrid MFC, however, is still far below the level for practical
applications. Further research to improve the cell performance needs to be
carried out in the future.

is manufactured by the anthraquinone process in a multistep
operation with high-energy consumption. The costly process and the toxicity
of organic solvents make this preparation route unfavourable. The production
of hydrogen peroxide through a fuel cell reactor is more economical, environ-
mentally friendly and with co-generat
