abstract = "Three zeolites (A, X and Y) with Ag incorporated in their cages are tested as bifunctional electrocatalysts
for direct borohydride fuel cells (DBFCs). Ag zeolites are characterised by XRD, FTIR, nitrogen sorption
and SEM, as well as by electrochemical methods. Ag zeolite shows good activity for the anodic reaction,
i.e., borohydride oxidation reaction (BOR) in alkaline media, presenting low onset potential and high
current densities. BOR kinetic and faradaic parameters at AgY are calculated, with the number of
exchanged electrons being 4.3. The BOR at AgY was found to be of 0.6 order with respect to BH4
concentration with an activation energy of 13 kJ mol 1. Regarding ORR, AgX shows the best
performance with the highest current densities and good stability over time. A two-electron pathway is
observed for ORR at AgX and specific capacitance was calculated to be 5.61 F g 1. The DBFC
performance is investigated based on half-cell measurements of the AgY anode and Pt/C cathode",
