Resumo
Solid alkaline fuel cell (SAFC) has been studied as possible alternatives in the
production of electricity for portable and stationary applications. The oxygen
reduction reaction (ORR) is key electrochemical processes, because his low
kinetics decreases system efficiency. The main progresses in the cathodic side
have been related to the development and improvement of activity and stability.
In this way, non precious material has been studied, in the last years. Cobalt
oxides have been reported to exhibit good performance for ORR. However, cobalt
bimetallic can be more eficient catalysts for ORR, especially for its bifunctional
function. Some Ni-based electrocatalysts have shown relevant good results for
ORR in four-electron pathway. Song et al. Showed, for example, that Ni addition
into Ag-based electrocatalysts for ORR decreases the ORR overpotential, while an
increasing in the limiting current density is observed. In this way, a bimetallic
CoNi/ C was produced to be used as a cathode in alkaline fuel cell.
