Possibility of using NiCo2O4 alloy as catalyst for fuel electrode of hydrazine fuel cell

2017

Szerokie stosowanie ogniw paliwowych ograniczone jest głównie wykorzystywaniem drogich katalizatorów. Wyeliminowanie platyny umożliwiłoby szeroką komercjalizację tych ogniw. Artykuł przedstawia analizę elektroutleniania hydrazyny na katalizatorze NiCo2O4. Jako elektrolit wykorzystano wodny roztwór KOH. Pomiarów dokonano potencjostatem. Wykazano możliwość elektroutleniania hydrazyny na katalizatorze NiCo2O4. W każdym przypadku (dla wszystkich stężeń hydrazyny i 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 kosztó…
