Two-Side-Simultaneously-Observing Test System of Passive DMFC

摘要

In order to test passive direct methanol fuel cell and simultaneously observe anode and cathode of a fuel cell, we designed and built a test system. The test system consists of four units: temperature control unit, lighting unit, camera unit and test and data acquisition unit. With a two-floor placement design, we separated tested object and its close auxiliary components from other devices. The design is critical for changing inclination angle between outward normal of anode and gravity direction, which is important to the experiment. The control interface of the test system makes it suitable for a microgravity test system in NMLC (National Microgravity Laboratory Center). Considering the test system will be used for microgravity experiment besides routine normal gravity experiments, many specific issues have been taken into account.
