the study of surface fractality composite film poly pyrrol with different surfactants on copper plate with electrochemical technic

Fuel cells are one of the most promising power sources which among of different types of fuel cells, the proton-exchange membrane fuel cell, PEMFC, has advantages like relatively lowoperating temperature and water producing as the only byproducts of its overall electrochemical reaction in addition to high energy densities, high efficiencies and fast start-up which are common characteristics of all types of fuel cells [1,2]. copper plates are amultifunctional part of a PEMFC. Metallic copper plates have received considerable attention due to better mechanical properties, good machining, high electrical conductivity, gasimpermeability, acceptable material cost, improved manufacturability and applicability to massproduction there are several reports on the dependency of morphology and properties of polypyrrol to the electrochemical deposition methods [3]. To achieve different morphology,polypyrrol was electropolymerized on the surface commercial by galvanostatic, potentiostatic and potentiodynamic methods and alo, sodium dodecylsulfate, Dodecyltrimethylammonium bromide (DTAB) and Triton X-100 (TX100) were used in electropolymerization bath as anionic, cationic and nonionic surfactant additives, respectively.
