“…Lately, fuel cells have gained worldwide attention as efficient and environmentally friendly energy generators. Practically, they are integrated electrochemical devices widely used to convert the delivered chemical energy into its electrical counterpart via redox reactions (Yuan et al 2021). Regarding their efficacy for energy generation, they can be served as energy carriers.…”

Dihydrogen (H2), commonly named ‘hydrogen’, is increasingly recognised as a clean and reliable energy vector for decarbonisation and defossilisation by various sectors. The global hydrogen demand is projected to increase from 70 million tonnes in 2019 to 120 million tonnes by 2024. Hydrogen development should also meet the seventh goal of ‘affordable and clean energy’ of the United Nations. Here we review hydrogen production and life cycle analysis, hydrogen geological storage and hydrogen utilisation. Hydrogen is produced by water electrolysis, steam methane reforming, methane pyrolysis and coal gasification. We compare the environmental impact of hydrogen production routes by life cycle analysis. Hydrogen is used in power systems, transportation, hydrocarbon and ammonia production, and metallugical industries. Overall, combining electrolysis-generated hydrogen with hydrogen storage in underground porous media such as geological reservoirs and salt caverns is well suited for shifting excess off-peak energy to meet dispatchable on-peak demand.

“…Proton exchange membrane fuel cells (PEMFCs) have a great potential as an alternative energy source for stationary power application and transportation owing to low pollution and high efficiency. , Ionomers are utilized as proton exchange membranes to achieve the transfer of protons and water between the anode and cathode, which also act as binders of gas permeability and proton transport in catalyst layers. − …”

In the operation of proton exchange membrane fuel cells, its ionomeric-polymer membrane is easily attacked by free radicals, resulting in the degradation of performance. In this work, the chemical degradation effect of hydrated Nafion membranes on gas adsorption, diffusion, and permeation behaviors is evaluated by molecular dynamics and Monte Carlo simulation. The correlation of pore ratio, free volume, hydrophilic/hydrophobic interface as well as the connectivity of the hydrophilic domain of Nafion membranes with gas transport characteristics are revealed. The results demonstrate that large free volume, high large pore ratio, smooth hydrophilic/hydrophobic interface, and good connectivity of the hydrophilic domain are favorable for adsorption, diffusion, and permeability processes. The C−S bond and C−O−C bond attack of membranes can increase the gas adsorption amount, which becomes weak after the tertiary carbon is attacked.

“…Choosing a suitable material is subject to the temperature and media of the environment that the PEMFC will operate in. Yuan et al [160] investigated the aging of silicon rubber under alternative and direct current voltages. Tan et al [161] investigated the deterioration of different gasket materials in PEMFC, which was found to start with surface roughness and develop cracks with time.…”

Fuel cells (FCs) have received huge attention for development from lab and pilot scales to full commercial scale. This is mainly due to their inherent advantage of direct conversion of chemical energy to electrical energy as a high-quality energy supply and, hence, higher conversion efficiency. Additionally, FCs have been produced at a wide range of capacities with high flexibility due to modularity characteristics. Using the right materials and efficient manufacturing processes is directly proportional to the total production cost. This work explored the different components of proton exchange membrane fuel cells (PEMFCs) and their manufacturing processes. The challenges associated with these manufacturing processes were critically analyzed, and possible mitigation strategies were proposed. The PEMFC is a relatively new and developing technology so there is a need for a thorough analysis to comprehend the current state of fuel cell operational characteristics and discover new areas for development. It is hoped that the view discussed in this paper will be a means for improved fuel cell development.
