The invention relates to a method for measuring the pressure and/or molar mass of a gas in a housing, the measure being carried out via an acoustic sensor, said acoustic sensor at least one transducer (5), an electric system (8) connected to the transducer (5) and a coupling layer (6) for coupling the transducer (5) to the housing (1), said method comprising the following steps: generating using the transducer (5) an excitation acoustic signal that vibrates the housing (1) and the gas (2) in a wide frequency band; detecting with the transducer (5) a response acoustic signal characteristic of the vibrations of the housing and the gas; analysing the response electric signals from the transducer (5) using the system (8); and deriving, essentially based on the gas (2) resonance frequencies, the speed of the acoustic waves in the gas, the molar mass of the gas and the pressure thereof. The invention also relates to an assembly for implementing the method.

Abrégé

The invention relates to a 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 peroxide. 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. Method of implementing such a device. Gaseous diffusion electrode that includes such a catalyst.
