“…While the SOC drops to less than 90% for most of the times for H 2 supply temperature of 15 C and very close to the desired range for 0 C at higher filling rates. The error of the results relative to the NIST data is determined using Equations (22) and (23).…”

Hydrogen fuel cell vehicle provides the significant advantage of high energy conversion efficiency and zero emission. Efficient hydrogen storage methods are vital for successful implementation of the hydrogen‐related technologies. Compressed hydrogen storage has been considered as a promising option in recently commercialized hydrogen fuel cell vehicles. The short filling time and high state of charge of compressed hydrogen storage tank are an essential requirement for fuel cell vehicles. This study presents the detail investigation of refueling compressed storage tank using computational fluid dynamics simulation and heat capacity model. The goal of the simulation is to identify the end temperature and state of charge. Initially, the mathematical model of end temperature and state charge is formulated. Later, the overall heat transfer involved in the refueling process is investigated by heat capacity model based on MC method defined by SAE J2601. The density obtains from the simulation is compared with the National Institute of Standards and Technology database. The SE in simulated results for the state of charge is reduced to <1% after applying the heat capacity method. The results may shade light on better understanding the refueling process of compressed hydrogen storage for fuel cell vehicle.

“…By contrast, in the present paper, the opportunities for passive thermal coupling of these two components, by using heat pipes without any additional energy-consuming devices (i.e., to carry the fuel cell heat to the MH canisters), is experimentally investigated. While heat pipes are commonly used for cooling electronic equipment [51,52,[75][76][77][78], only limited reported examples can be found in the literature (even at R&D stage) in which heat pipes have been used for either cooling of fuel cells [57,59,60,79,80], or heating up MH canisters [81][82][83]. The studies conducted on the use of heat pipes for fuel cell cooling, suggested the uniform temperature distribution across the stack and membrane and less weight and volume (i.e., at a system level) to be the key advantages of this approach [60,79].…”

This paper reports on an experimental investigation of a passive thermal coupling arrangement between a Proton Exchange Membrane (PEM) fuel cell and a Metal Hydride (MH) hydrogen storage canister using heat pipes for enhancing the release rate of hydrogen. The performance of this arrangement was measured by inserting the evaporator sections of the heat pipes into an aluminum plate mimicking one out of five cooling plates of a 500-W fuel cell (that is a 100 W section of the stack). Thermal pads were attached on both sides of the plate to represent the fuel cell heat to be supplied to a 660-sl MH canister. The results showed that the operating temperature of the fuel cell can be maintained in the desired range of 60-80 • C. A complementary experimental study was also conducted on an 800-sl MH canister supplying hydrogen to a 130-W fuel cell stack (a slightly scaled-up setup compared to the first experiment). The study confirmed the findings of an earlier theoretical study by the authors that by supplying about 20% of the total cooling load of the stack to a MH canister, its maximum sustainable hydrogen supply rate increased by 70%, allowing for continuous operation of the stack at its rated power.
