Peroxide power : Neutral solutions of H 2 O 2 can be produced directly and safely from O 2 and H 2 by using a fuel cell reaction. The most active and efficient cathode is a vapour‐grown carbon fibre (VGCF) electrode coated with Co‐tetraphenylporphyrin (0.05 wt %) on VGCF (2 mg cm −2 ). A maximum concentration of 13.5 wt % (4.0 M ) H 2 O 2 is obtained under optimized conditions at 278 K.
