Excessive energy is released and can be utilized from the oxidation of hydrogen. A fuel cell is a device that produces electricity based on this reaction, and is expected to be an efficient, clean energy conversion device since it produces only water as a by-product.
In sub-issue B, we focus on how to enhance the efficiency and durability of fuel cells. Our target is to develop novel design tools that can simulate the design, fabrication and aging processes. In order to attain this target, large-scale simulation tools for gas-liquid two-phase flows and electrodes are strongly demanded. These simulations have not been possible using conventional computational environments, but will be carried out using the computing power of the post-K computer.
Target
Improvement of fuel cell design process by simulating large-scale gas-liquid two-phase flow and electrodes.
Challenges
It is very difficult to directly observe microscopic phenomena and structures inside fuel cells, e.g., reactions that occur or the microstructure that is present in the vicinity of local three-phase boundaries (TPBs). Given the absence of empirical parameters, it is therefore challenging to model local TPB reactions, despite the importance of doing so. There is a strong need in the industry for an improved design process based on high-performance computing technology that can handle complex multiscale phenomena. It is therefore of the utmost importance to develop numerical simulation tools that can enhance the competitiveness of the fuel cell industry by improving components such as electrodes and stacks.
