Product description

During operating of fuel cells not only power but also heat will be generated. The heat hast to be removed in an appropriate way. In current systems this will be done by water cooling. To maintain an equally distributed temperature high flow rates are necessary. This is especially important for PEM fuel cells.
The same effect can be achieved more efficiently by evaporative cooling using a single component coolant. At the same time the removable heat flux is significantly higher. If this can be operated by natural convection, also a pump will be no longer necessary. This principle was first investigated by Garrity.

This project is designated to investigate the heat removal in a fuel cell by using evaporative cooling and natural circulation. For first observations a model plate was manufactured having micro channels for the refrigerant to flow. For this investigation only natural refrigerants will be used. The experimental set-up includes besides to the model plate a condenser and a tank for the liquid refrigerant. Later on experiments with real bipolar plates and with a real stack are planned.

Basically this principle of cooling is also suitable for automotive or domestic batteries during charging or in high duty.
