Studies on the selective catalysis of the electrode reactions in the H2/Br2 storage system

Summary

Considerable rates are obtained for the hydrogen electrode reactions using WC-gas-diffusion electrodes which are not impaired by active Br2 in the solution. Tafel-lines withb-values of appr. 30 mV for both, anodic and cathodic current density potential curves, can be attributed to the Tafel-reaction as the rate controlling step. High reversibility (very low polarization) of the Br2/2 Br− redox couple is observed at activated carbon plastic composite material. The presence of H2 does not influence the electrode behavior. The use of both substrates in the H2/Br2 storage system provides definite advantages of the conceptual design and operation due to their electrocatalytic selectivity.
