Educational Psychology Research and Practice (EPRaP): Volume 7, Issue 2

Educational Psychology Research and Practice is an open access periodical published twice a year by the School of Psychology, University of East London. It offers a forum for informed debate and discussion of Educational Psychology research and training as well as a wider focus on issues of social justice and civic engagement in applied psychological practice. EPRaP is open to publishing research findings, literature reviews, commentaries, methodology papers, reflection on practice and book/resource reviews. It is part of a research and learning culture that recognises the importance of knowledge exchange and impact for partners in the community

Self-feeding paper based biofuel cell/self-powered hybrid μ-supercapacitor integrated system

© 2016 Elsevier B.V. For the first time, a paper based enzymatic fuel cell is used as self-recharged supercapacitor. In this supercapacitive enzymatic fuel cell (SC-EFC), the supercapacitive features of the electrodes are exploited to demonstrate high power output under pulse operation. Glucose dehydrogenase-based anode and bilirubin oxidase-based cathode were assembled to a quasi-2D capillary-driven microfluidic system. Capillary flow guarantees the continuous supply of glucose, cofactor and electrolytes to the anodic enzyme and the gas-diffusional cathode design provides the passive supply of oxygen to the catalytic layer of the electrode. The paper-based cell was self-recharged under rest and discharged by high current pulses up to 4mAcm−2. The supercapacitive behavior and low equivalent series resistance of the cell permitted to achieve up to a maximum power of 0.87mWcm−2 (10.6mW) for pulses of 0.01s at 4mAcm−2. This operation mode allowed the system to achieve at least one order of magnitude higher current/power generation compared to the steady state operation
