Hydrogen detection method for use in e.g. chemical and petrochemical industries involves measuring electrochemical impedance between metallic surface and electrolyte solution using cell

NOVELTY – A metallic surface is placed in contact with an electrolyte solution consisting of NaOH. A cell measures the electrochemical impedance of the metal/solution interface to detect if hydrogen is absorbed in the interface and diffused through the metallic structure. USE – For use in e.g. chemical and petrochemical industries.

Main Application Field

E36 (Non-metallic elements, semi-metals (Se, Te, B, Si) and their compounds (except for E35).); J04 (Chemical/physical processes/apparatus – including catalysis, catalysts (excluding specific e.g. enzymatic or polymerisation catalysts), colloid chemistry, laboratory apparatus and methods, testing, controlling, general encapsulation, detection and sampling (excluding clinical testing) (B01J, L).); S03 (Scientific Instrumentation)
