摘要: The cost and availability of platinum, together with degradation phenomena that are directly or indirectly caused by the use a precious-metal catalyst, major obstacles to commercialization incumbent polymer electrolyte membrane fuel cell (PEMFC) technologies. Flowcath® technology is highly promising alternative conventional PEMFC avoids many these issues. While anode resembles cell, novel cathode employs liquid-based polyoxometalate redox mediator entirely free any precious metals. A transition-metal based centre within undergoes reversible reduction in regenerated externally using air. In this paper, performance for different catholyte flow rates concentrations described first model developed validated. voltage losses quantified compared values employing standard electrode assembly.
