Self-sustainable protonic ceramic electrochemical cells using a triple conducting electrode for hydrogen and power production

Probing novel triple phase conducting composite cathode for high performance protonic ceramic fuel cells

A key obstacle to practical operation of protonic ceramic fuel cells (PCFCs) is the development of high efficient cathode materials. In this study, we report the identification of Gd0.1Ce0.9O2-d (GDC) infiltrated PrBaCo2O5þd (PBC) e BaZr0.1Ce0.7Y0.2O3-d (BZCY) materials as a novel triple phase (e /Hþ/O2 ) conducting composite cathode of PCFCs. This triple phase conducting composite cathode is c...

Electrochemical sensor for neurotransmitters at physiological pH using a heterocyclic conducting polymer modified electrode.

We report the simultaneous determination of two neurotransmitters, norepinephrine (NEP) and serotonin (5-HT), at physiological pH using the electropolymerized film of 3-amino-5-mercapto-1,2,4-triazole modified glassy carbon (p-AMTa) electrode. A bare glassy carbon (GC) electrode fails to resolve the voltammetric signals of NEP and 5-HT due to the surface fouling caused by the oxidized products ...

Double perovskite cathodes for proton-conducting ceramic fuel cells: are they triple mixed ionic electronic conductors?

18O and 2H diffusion has been investigated at a temperature of 300 °C in the double perovskite material PrBaCo2O5+δ (PBCO) in flowing air containing 200 mbar of 2H216O. Secondary ion mass spectrometry (SIMS) depth profiling of exchanged ceramics has shown PBCO still retains significant oxygen diffusivity (~1.3 × 10-11 cm2s-1) at this temperature and that the presence of water (2H216O), gives ri...

Electrochemical Investigation of DNA Adsorbed on Conducting Polymer Modified Electrode

Electrochemical production of Graphene Oxide and its application as a novel Hydrogen Peroxide sensor

Herein, graphene oxide is produced by electrochemical oxidation method from graphite rod to examine its hydrogen peroxide sensing ability. The electrochemically produced graphene oxide is characterized by SEM and XRD. A few layers of Graphene Oxide(GO) sheets and corrugations in graphene sheets appeared intensely crumpled and folded into a typical wrinkled structure after electrochemical oxidat...
