针对平板式微热光电系统，通过合理的分析和计算，给出了系统的一个极限尺寸以及相应的工作性能。研究过程中，系统完整的能量转换单元包括一个燃烧室．两个过滤层、两片光电池以及一个冷却通道，采用实验和计算分析相结合的方法，确定了各个部件的极限尺寸和相互位置，单元三个方向的总体尺寸分别为10mm×8mm×2．5mm。随后通过建立的能量转换计算模型，对该尺寸下单元的各个性能参数进行计算，当氢氧混合气流量为1500mL／min时，具体性能数据为：单元电能输出为3．51w、总效率为1．74％、功率密度达到了17．55W／cm3，这充分论证了平板式微热光电系统充当微机械装置电源的可能性。
Based on the reasonable analysis and calculations, miniaturization limitations and corresponding performance are presented for the plane cell type miero-thermophotovoltaic system. One energy transition cell of this system included a combustor, two filters, two PV cells and one cooling channel, the minimum dimension and geometric relations of these parts are determined by analysing the results of experiments and calculations, the whole size of the energy transition cell is 10 mm×8 mm×2.5 mm. Then performance parameters of cell at this size are calculated by the established energy transition model, detailed performance data are as follows when hydrogen/oxygen mixture flux is 1500 mL/min： electricity output is 3.51 W, total efficiency is 1.74% and power density can reach to 17.55 W/cm3. The outstanding performance demonstrate the possibility to choose miero-thermophotovoltaic system as power sources of micro mechanical devices.
