Abstract
Solution casting method was used to develop a natural polymer electrolyte (NPE) based on iota carrageenan (iCG) using different amounts of NH4HCO2. Distilled Water was chosen as the solvent. The structural, thermal, electrical, and electrochemical analyses of the iCG: NH4HCO2 system confirmed its non-crystalline nature, low glass transition temperature (Tg = 48 °C), maximum DC conductivity and electrochemical stability (3.11 V). The maximum DC conductivity for the composition 1 g iCG: 0.4 wt% NH4HCO2 was observed to be 1.94 × 10−3 S cm−1. A primary proton battery (PPB) was constructed by sandwiching the optimum electrolyte between MnO2 as the cathode and Zn/ZnSO4·7H2O as the anode to evaluate the efficiency of the 1 g iCG: 0.4 wt% NH4HCO2 NPE. Additionally, a single PEMFC was fabricated with 1 g iCG: 0.4 wt% NH4HCO2 NPE. An OCV for PPB and PEM fuel cell were found to be 1.60 V and 616 mV, respectively.
期刊介绍：
This interdisciplinary journal is devoted to the physics, chemistry and materials science of diffusion, mass transport, and reactivity of solids. The major part of each issue is devoted to articles on:
(i) physics and chemistry of defects in solids;
(ii) reactions in and on solids, e.g. intercalation, corrosion, oxidation, sintering;
(iii) ion transport measurements, mechanisms and theory;
(iv) solid state electrochemistry;
(v) ionically-electronically mixed conducting solids.
Related technological applications are also included, provided their characteristics are interpreted in terms of the basic solid state properties.
Review papers and relevant symposium proceedings are welcome.
