Z. Abdin,Z. Abdin,Ali Zafaranloo,Ahmad Rafiee,Walter Mérida,Wojciech Lipiński,Kaveh Rajab Khalilpour,Kaveh Rajab Khalilpour +7 more
TL;DR: In this article, the authors present a critical review of the current state of the arts of hydrogen supply chain as a forwarding energy vector, comprising its resources, generation and storage technologies, demand market, and economics.
Journal ArticleDOI
Hybrid energy systems for off-grid power supply and hydrogen production based on renewable energy: A techno-economic analysis
Z. Abdin,Walter Mérida +1 more
TL;DR: In this paper, the minimum cost of energy (COE) for five different global locations (Squamish, Canada, Los Angeles and Golden, USA; and Brisbane and Adelaide, Australia) based on renewable energy systems was determined.
Journal ArticleDOI
Characterisation of proton exchange membrane fuel cell (PEMFC) failures via electrochemical impedance spectroscopy
TL;DR: In this paper, two PEMFC failure modes (dehydration and flooding) were investigated using in situ electrochemical impedance spectroscopy (EIS) on a four-cell stack under load.
