Abstract

Water soluble biomimetic models of Riboflavin (B2 vitamin) and Folic acid (B8 vitamin) demonstrated to be good oxidant of formic acid at various pH. Their usage as anolyte mediators in a flow fuel cell to convert formic acid (or formate) into electricity is validated with measured power densities up to 16 mW.cm^− 2. These preliminary optimum conditions demonstrated a volumetric energy density of 0.68 Wh.L^− 1 when operating at 5 mA.cm^− 2 and neutral pH. These new conditions inspired from redox flow batteries processes permit to remove noble metals at both sides of the formate flow fuel cell.

仿生电解质介导甲酸流动燃料电池(MFAFFC)

核黄素(B2维生素)和叶酸(B8维生素)的水溶性仿生模型被证明在不同ph值下是甲酸的良好氧化剂。它们在流动燃料电池中用作阳极电解质介质，将甲酸(或甲酸)转化为电能，测量功率密度高达16 mW.cm - 2。这些初步的最佳条件表明，体积能量密度为0.68 Wh。工作在5ma时，L−1。这些受氧化还原液流电池工艺启发的新条件允许在甲酸流燃料电池的两侧去除贵金属。图形抽象
