The increasing demand for more efficient cooling options in the areas of fuel cell technology motivates the development of novel cooling strategies with improved heat transfer. Cooling through phase transition of the coolant from the liquid to the gaseous state is therefore a suitable approach. In this context, the phase transition behaviour in the inner structure of bipolar plates, which is determined by the flow field and its surface properties, must be understood and designed as a central functional element for cooling in a fuel cell.
For the integrated development of a metallic bipolar plate based on the phase change cooling with modified surfaces, this paper discusses the design of the flow field, the design of the associated forming technology as well as the coating technology that meets the requirements of the bipolar plates with phase change cooling principle. In this regard, the wetting and the corrosion behaviour of different surface coatings and the in-situ phase transition behaviour within the bipolar plates are demonstrated and discussed.
