Modelling and analysis of a direct ascorbic acid fuel cell

摘要: Abstract l -Ascorbic acid (AA), also known as vitamin C, is an environmentally-benign and biologically-friendly compound that can be used alternative fuel for direct oxidation cells. While ascorbic cells (DAAFCs) have been studied experimentally, modelling simulation of these devices overlooked. In this work, we develop a mathematical model to describe DAAFC validate it with experimental data. The formulated by integrating the mass charge balances, parameters are estimated best-fitting data current–voltage curves. By comparing transient voltage curves predicted dynamic experiments, further validated. Various affect power generation simulation. cathodic reaction found most significant determinant generation, followed feed concentration mass-transfer coefficient acid. These studies reveal density steadily increases respect concentration. results may guide future development operation more efficient DAAFC.
