Special Issue Information

Dear Colleagues,

In our daily lives, everything we do involves energy. Energy is an engine of prosperity and an agent of progress. However, energy must be continuously generated from a primary source to perform actual work and requires some form of storage to equal the supply and demand. Energy also needs to change form to applicate to our daily lives usages. As one of the major applications of the promising energy storage vector-hydrogen, fuel cell can produce electricity without emitting pollutants or greenhouse gases. Fuel cell systems can be used in a wide range of applications, such as portable, transportation, and stationary utilizations. The excessive use of energy has pushed forward the research in the area of energy storage and fuel cell systems as the energy application. 

This Special Issue aims to present and disseminate the most recent advances related to the theory, design, modelling, control, and application of all types of energy storage and fuel cell systems.

Topics of interest for publication include, but are not limited to:

  • All kinds of chemical energy storage, physical energy storage and fuel cell, among others;
  • Hydrogen energy;
  • Energy efficiency;
  • Fuel cell system and its application;
  • Applications of energy storage.

Generally, the unit cell in a proton exchange membrane fuel cell (PEMFC) stack is divided into different zones according to the characteristics of the bipolar plate. There is a zone that has been neglected, which we define as the “neck zone” for the first time in this work. Uneven stress and deformation are prone to appearing in the neck zone due to its unique structure. A three-dimensional finite element model was applied to study the influence of the membrane electrode assembly (MEA) frame materials on the mechanical characteristics of the neck zone. In addition, the sealing and the water–gas transport performances of the neck zone were evaluated via the stress fluctuation and deformation. It was found that even with the commercial polyethylene naphthalate (PEN) frame, a leak point would be generated at the region with the lowest stress, reducing the performance and even causing safety hazards. The invasion rate was proposed to assess the water–gas transport ability. When an inappropriate frame material was adopted, the invasion rate went up to 32.4%, severely hindering the water and the air transport. It was concluded that MEA frames with a higher elastic modulus and thickness are preferred for the neck zone to obtain a high property of sealing and water–gas transport. Full article
