Popis:	Catalytic and direct synthesis of a neutral hydrogen peroxide solution from O2 and H2 was studied using a new conceptual PEMFC reactor with a new active cathode. A particular electrocatalyst of Co-TPP/vapor-grown-carbon-fiber (VGCF) heat-treated in He at 1073 K was found for two electrons reduction of O2. The most active and efficient cathode was 0.05 wt.%Co-TPP/VGCF (2 mg cm−2) coated on the VGCF base electrode. The maximum concentration of 13.5 wt.% was obtained with 42% CE at 278 K.
