“…AC is an environment-friendly cooling technology with less electrical consumption, noise, vibration, and negative environmental impact compared to conventional vapour-compression chillers. AC can be powered by a low-temperature heat source (80-200 • C) making them an ideal technology to be used for low-grade WHR, such as that in PEMFC [83][84][85]. Lithium bromide-water (LiBr-H 2 O) and water-ammonia (H 2 O-NH 3 ) mixtures are commonly utilized as operation solutions, i.e., absorbent-refrigerant pairs, in AC chillers.…”

Significant research efforts are directed towards finding new ways to reduce the cost, increase efficiency, and decrease the environmental impact of power-generation systems. The poly-generation concept is a promising strategy that enables the development of a sustainable power system. Over the past few years, the Proton Exchange Membrane Fuel Cell-based Poly-Generation Systems (PEMFC-PGSs) have received accelerated developments due to the low-temperature operation, high efficiency, and low environmental impact. This paper provides a comprehensive review of the main PEMFC-PGSs, including Combined Heat and Power (CHP) co-generation systems, Combined Cooling and Power (CCP) co-generation systems, Combined Cooling, Heat, and Power (CCHP) tri-generation systems, and Combined Water and Power (CWP) co-generation systems. First, the main technologies used in PEMFC-PGSs, such as those related to hydrogen production, energy storage, and Waste Heat Recovery (WHR), etc., are detailed. Then, the research progresses on the economic, energy, and environmental performance of the different PEMFC-PGSs are presented. Also, the recent commercialization activities on these systems are highlighted focusing on the leading countries in this field. Furthermore, the remaining economic and technical obstacles of these systems along with the future research directions to mitigate them are discussed. The review reveals the potential of the PEMFC-PGS in securing a sustainable future of the power systems. However, many economic and technical issues, particularly those related to high cost and degradation rate, still need to be addressed before unlocking the full benefits of such systems.

“…Nanofluids exhibit a large heat-transfer capacity and high thermal conductivity, and they can significantly change interfacial wettability after adsorption at an interface [5][6][7]. Consequently, they are widely applied in heat exchangers [8][9][10][11], electronic component cooling [12][13][14], fuel cells [15,16], and nuclear reactors [17]. In the future, nanofluids are likely to become efficient heat-transfer working fluids.…”
