Electrochemical oxidation of borohydride at nano-gold-based electrodes: Application in direct borohydride fuel cells

Oxygen reduction on carbon supported Pt and PtRu catalysts in alkaline solutions

“…Recently, interest in alkaline electrocatalysis has been increasing due to new developments in alkaline fuel cells (AFCs) [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. AFCs directly employing hydrogen or alcohols as fuels are promising power supplies for electronic portable applications.…”

Rotating ring-disc electrode (RRDE) investigation of borohydride electro-oxidation

“…Various fuel cells are being developed as portable power sources to meet higher energy demands as well as to extend the operational hours of these devices [3][4][5][6][7][8][9][10]. Liquid fuel cells such as direct methanol fuel cells (DMFCs) are attractive due to the higher energy-density of the liquid fuel and their ease of integration with portable devices.…”

A direct borohydride–peroxide fuel cell using a Pd/Ir alloy coated microfibrous carbon cathode

“…Several anode materials have been proposed to extract the 8 electrons from the BH À 4 ion [6][7][8][9] but gold is considered to be amongst the most effective [10]. The oxidation of BH À 4 ions at 100 nm sized gold nanoparticles on a gold-plated nickel grid (<0.8 mg cm À2 ) and on a commercial Au electrode (1.8-2.0 mg cm À2 ) was compared [11,12]. The Au nanoparticles on the Ni-supported electrode showed a higher activity than the commercial gold electrode.…”
