Special Issue Information

Dear Colleagues,

Modeling and simulation are key tools in the design and development of fuel cells and electrolyzers. Recent advances in high-performance computation have promoted the application of modeling and simulations, which are now being used to tackle real-world problems.  As such, this Special Issue is devoted to “Modeling and Simulation of Fuel Cells and Electrolyzers”. The scope is broad, covering modeling and simulation on all levels, ranging from nano to micro to macro scales. Design, characterization, and optimization of fuel-cell materials, stacks and systems are all suitable topics for this Special Issue. Papers presenting a model with no verification or validation of the model or results will not be considered for review.

All types of articles are welcome. Three-page mini-articles, perspectives, opinions, and short communications will also be considered, provided they address a current challenge to fuel-cell commercialization or propose a new idea. Review articles discussing various types of modeling and/or simulation of fuel cells and electrolyzers are particularly welcome.

Proton exchange membrane water electrolyzers (PEMWEs) coupled with renewable energy resources are considered to be a key technology for producing green hydrogen. However, the high current density PEMWE operation features remarkable voltage losses. A significant part of these losses is due to the mass transport resistance in the PEMWE. Even though the importance of mass transport resistance is widely recognized, it is still poorly understood. Currently, the two-phase transport through the anode porous transport layer (PTL) and catalyst layer is considered to be the main cause of the mass transport losses. In this work, a dynamic macroscopic mathematical model, coupling electrochemical reaction with mass transport through the PTL and flow channels, has been developed to study the two-phase flow in the PTL and mass transport losses of a PEMWE. The influence of the current density, inlet water flow rate, PTL structural parameters, and capillary pressure curve was evaluated. The existence of the critical current density was observed, as well as its dependence on the operating parameters and PTL structure. Even though the results show that the PTL structure has a significant influence on the PEMWE performance, they indicate that a better mathematical description of the two-phase flow in the PTL is necessary.
