Stud y the effe ct of car bon active as an ad ditve to the cataly st layer o f gas diffusion electr ode on th e ORR k inetic.

One of the main problems of the comme rcialization of fuel cells is makin g electrode s .If the electro des can be produced with desired properties, performance and reasonable price, making large – sc ale fuel cell would be possible[۱]. One way that increases the perf ormance of the electrodes can be increasing the surface a rea of catalyst layer that studied in this research by additi on of different amounts of activated carbon. Sulfuric ac id ۲.۵ M w as used as electrolyte, Ag/AgCl electrode as reference elect rode and Pt electrode a s counter electrode [۲]. Pt loading in all electrodes was ۰.۳ m g.cm-۲[۳].
