Abstrakty
The use of fuel cells on a large scale is mainly limited by the high cost of catalysts. Elimination of platinum as catalyst would allow for wider commercial application of fuel cells. The paper presents a study of hydrazine electrooxidation on NiCofi^. So, the work shows a possibility of use of NiCofl^ alloys as catalysts for anode of hydrazine fuel cells. Researches were done in glass vessel on an electrode with NiCo2Oi alloy as a catalyst. An aqueous solution ofKOH was used as the electrolyte. Measurements were done with the use of potentiostat. Conducted measurements show that there is a possibility of electrooxidation of hydrazine with NiCopi catalyst. In any case, the process of electrooxidation of hydrazine occurs. A current density of about 15-35 mA/cm2 has been obtained for all concentrations of hydrazine and electrolyte. The current density is low, but the price of this catalyst is much lower than platinum The using catalyst with 15 and 25% of Co provides obtained higher current density than using catalyst with 50 and 75% of Co. So, the work shows possibility to use /V/Co-,0. alloy as catalysts for fuel electrode of hydrazine fuel cells.
Szerokie stosowanie ogniw paliwowych ograniczone jest głównie wykorzystywaniem drogich katalizatorów. Wyeliminowanie platyny umożliwiłoby szeroką komercjalizację tych ogniw. Artykuł przedstawia analizę elektroutleniania hydrazyny na katalizatorze NiCop. lako elektrolit wykorzystano wodny roztwór KOH. Pomiarów dokonano potencjostatem. Wykazano możliwość elektroutleniania hydrazyny na katalizatorze NiCo2Ot. W każdym przypadku (dla wszystkich stężeń hydrazyny! udziałów Co) proces elektroutleniania zachodził. Gęstość prądu wynosiła 15-35 mA/cm2 dla wszystkich koncentracji hydrazyny i elektrolitu. Gęstość prądu jest niewielka, jednak koszt uzyskania katalizatora jest znacznie niższy od kosztów platyny. Gęstość prądu jest wyższa dla stopów o 15 i 25% udziale Co, niż stopów o 50 i 75% udziale Co. Wykazano więc możliwość wykorzystania stopu NiCopi jako katalizatora anody w hydrazynowym ogniwie paliwowym.
