High power density along with low gravimetric and volumetric characteristics for Proton Exchange Membrane Fuel Cell stacks are needed in order to be successfully implemented on the market. It is well known that the heat transfer coefficients with liquid flow are much higher than airflow for the same pumping power, therefore liquid cooling is currently the most widely used cooling strategy in high power PEMFC stacks. This paper presents the manufacturing steps and preliminary tests results for an in house production of graphite type bipolar plates with liquid cooling circuit for PEMFC stacks.
