燃料电池的微尺度测试技术

Micro-scale measuring and testing techniques for fuel cells

随着燃料电池体积的微小化,传统的测试技术已经不再适合微型燃料电池某些参数的测试。在这种情况下,基于微机电系统的微尺度测试技术被逐步引入燃料电池的测试中。本文对燃料电池的温度、湿度及燃料浓度等参数的微小型测试技术进行了回顾,同时也对引入显微镜等设备的微型燃料电池可视化系统进行了讨论。最后对燃料电池的微尺度测试技术发展前景进行了分析。

With the microminiaturization of fuel cells, the traditional testing techniques is no longer suitable to some parameters test for micro fuel cells. Therefore, micro-scale measuring and testing techniques based on micro-electromechanical systems （MEMS） is introduced into fuel cells measurement. In this paper the measurement methods for temperature, humidity and concentration testing in fuel cells are reviewed. Visualization system of two-phase flow based on microscopy for micro fuel cells is discussed. And the long-term potential of micro scale measuring and technologies for fuel cells are also analyzed.
