“…Originally proposed by Galloway and Mudawar [15,16], the Interfacial Lift-off Model has been validated in several studies that were performed in both Earth gravity [33,34,37] and microgravity [38][39][40] over a wide range of operating conditions using both CHF data and high-speed video. Shown in Fig.…”

“…Konishi et al [40] extended the model by Zhang et al [33] to double-sided heating for subcooled inlet conditions. As subcooled liquid enters the heated section of the channel, two vapor layers begin to form at the leading edges of both heated walls surrounding a middle liquid layer.…”

“…Konishi et al [26] described how formation of the wetting fronts responsible for cooling of the heated wall prior to CHF relies on interfacial instability of the wavy vapor layer adjacent to the heated wall. For an unstable interface, the critical wavelength, k c , is derived from the critical wave number, k c , which is given by…”

“…Narcy et al [41] experimentally studied the forced convection boiling behaviors of HFE-7000 in normal gravity and microgravity, and they also analyzed the flow pattern and heat transfer behaviors inside the flow channels. Konishi et al [42,43] studied the flow boiling behaviors of FC-72 in microgravity and analyzed the effects of different operating condition on the flow boiling behaviors under different gravity conditions. Jong et al [44] investigated the twophase annular flow under different flow behaviors in microgravity using the film thickness time trace measurements.…”

h i g h l i g h t sMicrogravity experiments are operated at lower temperature. Channel orientations affect the performance of PEMFCs in a microgravity environment. Water in vertical channels is easily expelled in microgravity environment. Gravity slightly affects the two-phase flow behaviors of PEMFCs with horizontal channels. In this work, proton exchange membrane fuel cells (PEMFCs) with transparent windows are designed to study the gas-liquid two-phase flow behaviors inside flow channels and the performance of a PEMFC with vertical channels and a PEMFC with horizontal channels in a normal gravity environment and a 3.6 s short-term microgravity environment. Experiments are conducted under high external circuit load and low external circuit load at low temperature where is 35 C. The results of the present experimental work demonstrate that the performance and the gas-liquid two-phase flow behaviors of the PEMFC with vertical channels exhibits obvious changes when the PEMFCs enter the 3.6 s short-term microgravity environment from the normal gravity environment. Meanwhile, the performance of the PEMFC with vertical channels increases after the PEMFC enters the 3.6 s short-term microgravity environment under high external circuit load, while under low external circuit load, the PEMFC with horizontal channels exhibits better performance in both the normal gravity environment and the 3.6 s short-term microgravity environment.
