Abstract

This paper reports a computational demonstration and analysis of an innovative up-scaling counter-flow based microfluidic network to convert formic acid into electricity. This design consists of multi-dimensional T-shaped micro-scale channels that allow the inflow of liquid catholyte and anolyte from oppositely positioned inlets. It is revealed that the up-scaling strategy could effectively form primary and secondary counter-flow patterns, which are beneficial for high power output and fuel utilization at low flow rate operation. The design shows a breakthrough of the overall energy throughput and reactivity because of the full engagement of all available reaction sites. The energy loss mechanism introduced by the up-scaling network is also examined, demonstrating its performance intensification effect.
