Comprehensive review shows only 10 % focus on FCHEV thermal challenges. • Identified research gaps for thermal management in FCHEVs. • Over 70 % of studies overlook thermal subsystem interdependencies. • Waste heat recovery can boost FCHEV efficiency up to 90 %. • WHR increases driving range by ~11 % in cold weather conditions. A R T I C L E I N F...
Battery electric vehicles are pivotal in advancing the circular economy by reducing carbon footprints through their sustainable design and low-emission operations. The growing demand for electric vehicles with fast-charging capabilities and high-energy-density Li-Ion batteries has significantly intensified the importance of effective battery therma...
In this work, the effect of low air relative humidity on the operation of a polymer electrolyte membrane fuel cell is investigated. An innovative method through performing in situ electrochemical impedance spectroscopy is utilised to quantify the effect of inlet air relative humidity at the cathode side on internal ionic resistances and output volt...
Flow field structure plays a vital role in water management and gas distribution within the proton exchange membrane fuel cell (PEMFC) and has always been the focus of fuel cell research. In-situ experiments are carried out using pure oxygen and air as cathode oxidants, performance tests, polarization curves, electrochemical impedance analysis, gas...
Flow field validates itself as one of the critical components having a significant impact on the performance of proton exchange membrane fuel cells (PEMFCs). This study experimentally analyses and compares the behavior of the wavy flow field designs with the serpentine, interdigitated, and straight-parallel flow field designs. In-situ experiments a...
This paper evaluates the liquid water at the gas diffusion layer-channel (GDL-channel) interface of reconstructed GDL microstructures with uniform and non-uniform fiber diameters in wave-like channels. A non-uniform GDL microstructure is reconstructed for the first time at the GDL-channel interface to evaluate droplet motion. The three-layer GDL mi...
In this study, the effect of membrane water content on proton exchange membrane (PEM) fuel cell cold start is investigated experimentally in detail. The cyclic voltammetry (CV) and high frequency resistance (HFR) are introduced to character electrochemical active surface area (ECSA) of the electrode and water content in the cell. Under normal condi...
A comprehensive steady-state model is developed to investigate the effects of electrode structure on the performance of solid oxide fuel cell, considering detailed heat and mass transfer processes, as well as electronic and ionic charge transport. The percolation theory is used to evaluate the effective transport properties in electrode. The unifor...
