This experimental study presents the design, development, and assembly of a lab-scaled modified reversible proton exchange membrane fuel cell (MRPEMFC), with an emphasis on heat management during electrolyzer mode operation (EMO) using cylindrical heat pipes (CHPs). Further, this paper discloses the integration procedure of CHPs on the external surface of both bi-polar end plates (BEPs) of the MRPEMFC. During testing of the developed cell without application of CHPs under EMO, an operational temperature of 55 °C is observed on the hydrogen-side bi-polar end plate (HSBEP), while 26 °C on the oxygen-side bi-polar end plate (OSBEP). Subsequent incorporation of CHPs on the HSBEP yields 18% decrease in operational temperature after 360 min of operation. On the OSBEP, the temperature difference with the implementation of CHPs is observed 1 °C lower than when CHPs are not implemented. This slight variance is due to the continuous supply of distilled water on this side. This passive cooling strategy not only enhances comprehension of temperature dynamics within the test cell but also expands the domain of thermal cooling for reversible fuel cells (FCs), making them suitable for diverse stationary and portable applications, particularly for remote area power supply.

摘要

This experimental study presents the design, development, and assembly of a lab-scaled modified reversible proton exchange membrane fuel cell (MRPEMFC), with an emphasis on heat management during electrolyzer mode operation (EMO) using cylindrical heat pipes (CHPs). Further, this paper discloses the integration procedure of CHPs on the external surface of both bi-polar end plates (BEPs) of the MRPEMFC. During testing of the developed cell without application of CHPs under EMO, an operational temperature of 55 °C is observed on the hydrogen-side bi-polar end plate (HSBEP), while 26 °C on the oxygen-side bi-polar end plate (OSBEP). Subsequent incorporation of CHPs on the HSBEP yields 18% decrease in operational temperature after 360 min of operation. On the OSBEP, the temperature difference with the implementation of CHPs is observed 1 °C lower than when CHPs are not implemented. This slight variance is due to the continuous supply of distilled water on this side. This passive cooling strategy not only enhances comprehension of temperature dynamics within the test cell but also expands the domain of thermal cooling for reversible fuel cells (FCs), making them suitable for diverse stationary and portable applications, particularly for remote area power supply.
