3-LAYER MEMBRANE ELECTRODE ASSEMBLY. A CATALYST COATED MEMBRANE MADE OF PLATINUM LOADED CARBON WITH IONOMER ELECTROLYTE MEMBRANE AND A PROTECTIVE FILM ON SURFACE FOR TRANSPORTATION. USED FOR ELECTROCHEMICAL COMPRESSORS, SENSORS, FUEL CELLS, BATTERIES, SUPER CAPACITORS, ELECTROLYSERS, DESALINATION AND DEHUMIDIFICATION. IT FORMS PART OF A 7-LAYER MEMBRANE ELECTRODE ASSEMBLY (MEA) WHICH IS PART OF A PROTON EXCHANGE MEMBRANE (PEM). THE PROTON PERMEABLE IONOMER MEMBRANE ALLOWS THE PASSAGE OF PROTONS TO FORCE THE ELECTRONS AROUND A CONDUCTIVE PATH WHICH CREATES AN ELECTRICAL CIRCUIT. THE CATALYST, AS AN ANODE, SPLITS THE MOLECULE INTO TWO PROTONS AND TWO ELECTRONS ALTERNATIVELY AND THE CATALYST, WHEN ACTING AS THE CATHODE, WILL CATALYSE THE FORMATION OF TWO OXYGEN IONS WHEN IT COMES INTO CONTACT WITH OXYGEN GAS TO FORM WATER. SINCE THE PROCESS OF HYDROGEN GAS REACTING WITH OXYGEN GAS IS SLOW, THE PLATINUM PROVIDES ACCELERATION. THE PRODUCT IS PRESENTED AS A SHEET OR ROLL SHAPE.

CLASSIFICATION HAS BEEN DETERMINED IN ACCORDANCE WITH THE FOLLOWING: GENERAL INTERPRETATIVE RULES (GIR)S: GIR 1 HAS BEEN USED TO CLASSIFY THIS PRODUCT BY THE TERMS OF HEADING 3815: REACTION INITIATORS, REACTION ACCELERATORS AND CATALYTIC PREPARATIONS, NOT ELSEWHERE SPECIFIED OR INCLUDED GIR 3B HAS BEEN USED AS THE PLATINUM IS CONSIDERED TO BE THE ACTIVE SUBSTANCE AND IS THEREFORE THE ESSENTIAL CHARACTER. GIR 6 HAS BEEN USED TO CLASSIFY THE GOODS TO SUBHEADING LEVEL 381512: SUPPORTED CATALYSTS; WITH PRECIOUS METAL OR PRECIOUS-METAL COMPOUNDS AS THE ACTIVE SUBSTANCE TARIC CODE 3815120090: OTHER THAN ELSEWHERE SPECIFIED ALSO CLASSIFIED IN ACCORDANCE WITH: SECTION VI NOTE 3 HARMONISED SYSTEM EXPLANATORY NOTES (HSEN) HEADING 38.15 NOTE (A) COMBINED NOMENCLATURE EXPLANATORY NOTES (CNEN) 3815 11 00 TO 3815 19 90
