Special Issue Information

Dear colleagues,

Thirty years ago, there were great expectations for the hydrogen fuel cell economy, but, in the following decades, it has experienced cycles leading society from excessive expectations to substantial doses of disappointment. Recently, electrification infrastructures have been growing very fast, and the main global automotive manufacturers are investing in electric cars, including hybrids, battery electric, and fuel cell electric, and consumer interest in zero-emission vehicles has arisen exponentially. There has been a radical change in social perceptions of hydrogen technologies in a short period of time. A growing body of evidence suggests that hydrogen fuel cells are appearing again as an attractive solution to reduce carbon dioxide emissions and the latest improvements are pointing towards their economic viability. This technology may provide energy independence, security, and resilience, and foster the use of local resources and strengthen domestic economies. Fuel cells are well established in certain niches and are already in use and advancing positions in real-world applications such as industrial-scale backup power systems, mobile power for electric trains, buses, material handling systems, and heavy-duty transport trucks. Hydrogen vehicles and fuel cell home heating systems are commercially available in several countries.

On the other hand, portable solutions for highly demanding consumer electronic applications are still pending on new developments, especially for hydrogen fuel storage solutions. They should be capable of repeatedly turning off and on and should have turndown capabilities required to match the dynamic power needs of the devices. For widespread adoption, portable power fuel cell systems should minimize lifecycle environmental impact through the use of reusable fuel cartridges, recyclable components, and low-impact manufacturing techniques. In general, challenges around cost and performance still remain, and further improvements are required for hydrogen production and storage technologies to become truly competitive, although competitiveness with other low or zero-emission technologies seems to be now more realistic.

For this Special Issue, we invite papers on innovative developments, including new materials, novel technologies and applications, reviews, case studies, and analytical and assessment papers relevant for the development fuel storage for hydrogen fuel cell systems. Topics of interest for publication include, but are not limited to the following:

  • Design and optimization of electrode materials, catalyst layers, electrolytes, and single cells for portable applications in PEMFC and SOFC technologies: application of novel nanostructures and advanced functional materials.
  • Alternative fuels for storage. Advances in catalytic and electrocatalytic processes for hydrogen production (reforming of fuels, dehydrogenation of liquid organic hydrides, controlled hydrolysis of compounds, etc.).
  • Development of portable power fuel cell systems.
  • Advances in manufacturing processes for cost reduction.
  • Novel portable applications and technology demonstrations: unmanned aerial vehicles, drones, portable electronics, radio control (RC) cars, boats, robot toys, emergency lights, military devices for communication, etc.
  • Approaches in direct and indirect hydrogen fuel storage methods for portable devices.
  • Original contributions covering life-cycle assessment (LCA) and sustainability of portable hydrogen fuel cell technologies, including their carbon footprint impact and socio-economic analyses.

A sustainability assessment regarding the manufacturing process and the use of a new proton exchange membrane fuel cell (PEMFC), specially designed for portable hydrogen applications, is presented. The initial fuel cell prototype has been configured by taking into account exclusively technical issues. However, a life cycle analysis considering environmental and socioeconomic impacts is crucial to improve the model to develop a more sustainable product. From the environmental perspective, the durability of the system and its efficiency are key elements required to decrease the potential overall impacts. High electricity consumption for manufacturing requires a commitment to the use of renewable energies, due to the high current value of the projected impact of climate change (42.5 tonnes of CO2 eq). From the socioeconomic point of view, the dependence of imported components required for the synthesis of some materials displaces the effects of value added and employment in Spain, potentially concentrating the largest impact on countries such as Singapore, Japan and the UK, whereas the cell assembly would have a greater benefit for the country of fabrication. These results provide a basis for new research strategies since they can be considered standard values for improving future upgrades of the fuel cell in terms of sustainability. Full article

A passive regulation system for the water content has been developed and evaluated for a proton exchange membrane fuel cell. It is of particular relevance for micro-fuel cells, whose volume, weight and extra-consumption of fuel and power for subsidiary components must be kept to a minimum. This solution consists of a self-regulating humidity system implemented at the anode chamber that allows free water exchange with the environment through the surface of a gas-tight membrane. The micro-fuel cell, which is designed according to the patent WO2015025070A1, has been assembled and operated under completely passive conditions. The behavior of the anode humidity regulation system has been analyzed externally and in situ. The external part of the anode, where the humidity exchange with the environment takes place, has been isolated in a closed chamber and a hygrometer has been used to register the relative humidity in the zone near to the water exchange film. The results obtained from the operation of this innovative system are discussed in the light of the water permeation behavior of different Nafion membranes. Full article
