“…Earlier studies on the thermal coupling of PEM fuel cells and MH canisters are reviewed in Section 2 of the present paper. This paper then focuses on an experimental investigation to study further the feasibility of this arrangement and confirm some of the results suggested earlier by a theoretical computer simulation [40] (Sections 3 and 4).…”

“…As mentioned before, the use of heat pipes for thermal management of fuel cells, or MH hydrogen storage canisters, have thus been studied as separate arrangements for each of these components in the past, but not as a combined system, to thermally couple the two components. An earlier theoretical study [40] tried to address this gap by developing a steady-state analytical model in MATLAB. The model was then applied on a 500-W PEMFC and five MH canisters (LaNi 5 , 660 sl) coupled using heat pipes.…”

“…When using MH hydrogen storage, more heat is demanded by the hydrogen canisters to increase their supply rate (i.e., to meet the fuel cell demand at higher power outputs). The fact that the fuel cell generates more heat at higher power operating points correlates very well with increased demand of heat by the MH canisters (i.e., to release hydrogen at a faster rate) [40]. Hence the potentially-attractive opportunity arises of thermal coupling of a PEMFC with the MH canister used to supply it.…”

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.

“…On the contrary of hydrogen absorption, hydrogen desorption (discharging) is endothermic process in which chemical bonds in solid MH are broken. Dissociation of chemical bonds in MH is endothermic process therefore it absorbs the heat . Hydrogen charging and discharging rate from the MH depends on the working temperature and pressure .…”

Techno‐economic analysis of metal hydride‐based energy storage system in microgrid

Hydrogen can be a promising option as an energy storage medium in renewable power generator‐based microgrid. However, the technologies used for the hydrogen storage such as high pressure in gaseous form and solid storages can significantly affect the cost performance of the hydrogen‐based microgrid. In this study, a techno‐economic assessment for solid hydrogen storage (metal hydride [MH])‐based microgrid in Indian operating conditions has been carried out in terms of levelized cost of electricity (LCOE), net present cost, and avoided environmental emissions. In the present microgrid, excess photovoltaic (PV) generator electricity is used to generate hydrogen using the alkaline water electrolyzer (EL). This generated hydrogen is stored in the MH cylinder. The stored hydrogen is converted back into electricity by fuel cell (FC) in case of insufficiency of PV electricity. The sizing of the microgrid components such as PV, FC, EL, and hydrogen storage tank are obtained for given load profile using HOMER optimization tool. An attempt has been made for the cost evaluation of the solid and high‐pressure gaseous storages in the microgrid. A comparative study between two energy storage mediums such as battery and hydrogen in microgrid is also performed. In case of battery and hydrogen storages, the LCOE is found to be 0.1293 and 0.383 $/kWh, respectively. It was found that battery storage system is more economical than hydrogen storage in microgrid. Nonetheless, the difference between the LCOE in hydrogen‐based microgrid is reduced considerably with optimized cost scenario of the EL, FC, and H2 storage tank as compared to the battery storage. Such technical, economic, and environmental assessment of the MH‐based microgrid system provides a firm basis to policymakers for shaping energy and environment policies for hydrogen activities.

Experimental analysis of dynamic performance of air‐cooled PEMFC stack integrated ultrathin vapor chambers under New European Driving Cycle

Ultrathin vapor chamber (UVC) is very suitable for the thermal management of proton exchange membrane fuel cell (PEMFC) stack due to the simple structure, high heat conduction, and excellent temperature uniformity. For exploring the application of UVC on the thermal management of the PEMFC stack, a contrast experiment is performed between two PEMFC stacks (one named conventional PEMFC stack and the other named UVC-PEMFC stack) under the New European Driving Cycle mode with different purge periods. Experimental results show that UVC can significantly improve thermal management. It mainly behaves in two aspects: (a) UVC can effectively remove the waste heat. Under 60% load, the removed waste heat reaches 10.52% of Q gen , which generates a temperature difference of 12.5% between the two stacks. The maximum temperature is decreased from 58 C to 42.5 C under 0.645 A/cm 2 and (b) UVC can also obviously improve the temperature uniformity. Under full load, the temperature uniformity of the UVC-PEMFC stack is 3.25 times lower than the conventional stack. The maximum temperature is decreased from 22 C to 3 C. The suitable working temperature and excellent temperature uniformity generate high efficiency, resulting in higher output power. For example, the output power of the UVC-PEMFC stack is 12.8% higher than the conventional PEMFC stack under 60% load. Unexpectedly, the long purge interval will reduce the dynamic response of the UVC-PEMFC stack under high current density. This investigation tries to provide an implication for a potential application of UVC on aircooling PEMFC stack without changing its concise system.dynamic performance, NEDC mode, PEMFC stack, thermal management, ultrathin vapor chamber | INTRODUCTIONWith the increase of the motor-vehicle population, the consumption of fossil fuels increases rapidly each year.According to the China Vehicle Environment Management Annual Report of 2019, 1 the usage of diesel and gasoline will increase by 150 million tons in the next 5 years in China.
