Hydrogen has the potential to be the sustainable fuel of the future, decrease the global dependence on fossil fuel resources, and lower the pollutant emissions from the transportation industry. In this study, recent development in hydrogen-based transportation engines is reviewed to scrutinize the feasibility of using hydrogen as a major fuel of future. Using hydrogen in internal combustion engines achieves only 20-25% efficiency and low power output compared to fossil-fueled internal combustion engines. Although hydrogen-based internal combustion engines have recently received considerable interests, several practical barriers have prevented the fast development of this technology. Hence, at the current stage, using hydrogen as an additive to hydrocarbon fuel systems have been taken into consideration to produce higher performance than hydrogen-only internal combustion engines. Using the dual-fuel strategy can increase the combustion stability and thermal efficiency while decreasing the CO and unburned hydrocarbons emissions, and fuel consumption. Alternatively, hydrogen can be used in fuel cells for vehicular applications with several automotive manufacturers producing fuel cell vehicles currently. Fuel cells can achieve efficiencies of up to 60%, while the rest is lost as heat. Strategies that have been investigated to increase the efficiency, performance, and lifespan of fuel cells are capillary pumping systems, a chemisorption chiller, nanofluids and supercapacitors. All such strategies improved the fuel cells in one or more ways. Safety, hydrogen delivery, onboard storage, and the capital and operating costs of hydrogen powered vehicles are analyzed to approach to clean transportation utopia.

Proton exchange membrane fuel cell (PEMFC) has the advantages of high energy efficiency, clean, pollution-free, fast start-up and noise-free, but its thermal management problems still restrict the development and practical application of PEMFC. This paper analyzes the important influence of heat management on the working performance of proton exchange membrane fuel cell, and summarizes the structure principle and effect evaluation of thermal management system using heat pipe under the premise of simply summarizing the shortcomings of the thermal management system using conventional cooling method. By expounding the working principle and characteristics of pulsating heat pipe, and from the perspective of PEMFC internal structure and technology, the feasibility of applying pulsating heat pipe to PEMFC thermal management system is analyzed, with a view to developing pulsating heat pipe-type PEMFC thermal management technology with compact structure and excellent performance.

“…[151] Besides, heat pipes can act as such a passive cooling system when using a material of high thermal conductivity. [152,153] As a last approach, FC stacks can be cooled by air. If not supplied by pure oxygen, cooled, compressed and humidified air is supplied to the cathode as a reactant gas.…”

The behavior of proton exchange membrane fuel cells (PEMFCs) strongly depends on the operational temperatures. In mobile applications, for instance in fuel cell electric vehicles, PEMFC stacks are often subjected to temperatures as low as −20 °C, especially during cold start periods, and to temperatures up to 120 °C during regular operation. Therefore, it is important to understand the impact of temperature on the performance and degradation of hydrogen fuel cells to ensure a stable system operation. To get a comprehensive understanding of the temperature effects in PEMFCs, this manuscript addresses and summarizes in‐ situ and ex‐ situ investigations of fuel cells operated at different temperatures. Initially, different measurement techniques for thermal monitoring are presented. Afterwards, the temperature effects related to the degradation and performance of main membrane electrode assembly components, namely gas diffusion layers, proton exchange membranes and catalyst layers, are analyzed.
