  "textContent": "Gaseous diffusion electrode, preferably cathode, and comprising a catalyst,used in a two-compartment electrolytic cell the compartments being separated by an ion exchange membrane, for the production of hydrogen peroside. The electrode comprises a catalytic layer, a support layer and a hydrophobic layer ; the support layer is inserted between the catalytic and hydrophobic layers. The catalytic layer comprises a catalyst consisting of a derivative of 5,10,15,20-tetrakis(4-methoxyphenyl)21H,23H Porphyrin Cobalt II(CoTMPP). The content of CoTMPP (as wt. of Co to C) is less than or equal to 0.5%, more preferaby 0.2% max. ; alternatively the catalyst comprises a compound based on Co, N and C prepared from a compound containing Co but not N, such as CoCl 2, CoCO 3, Co(OH) 2, CoSO 4or CoAc. Independent claims are also included for the apparatus and production process of hydrogen peroxide.",
