A novel modular thermophotovoltaic (TPV) power generator is presented, which is based on the sub-millimeter parallel plate combustor. It has the potential to achieve a high power density because of the high radiation energy per unit volume due to the high surface-to-volume ratio of the micro-combustor. The work experimentally investigated the ignition limitation for two micro-combustors. It also studied the effects of three major parameters on a sub-millimeter combustor, namely hydrogen to oxygen mixing ratio, hydrogen volumetric flow rate and nozzle geometry. The results show that the combustion efficiency decreases with the increase of the hydrogen flow rate, which is caused by reduced residence time. The average wall temperature with the rectangular nozzle is 25 K higher than that with the circle nozzle. The output electrical power and power density of the modular TPV power generator are projected to be 0.175 W and 0.0722 W cm-3 respectively. We experimentally achieve 0.166 W of electrical power, which is in good agreement with the model prediction. © 2010 IOP Publishing Ltd.||Source Title:||Journal of Micromechanics and Microengineering||URI:||http://scholarbank.nus.edu.sg/handle/10635/85401||ISSN:||09601317||DOI:||10.1088/0960-1317/20/12/125021|
