This project aims to optimize the electrical-to-chemical energy conversion efficiency of a high throughput electrolyzer. The project will focus on a water splitting electrolyzer which produces gaseous hydrogen and oxygen, that are generated at a cathode and anode electrodes, respectively. The electrodes are made of a foam material and the electrolyte is flown through them to facilitate the extraction of the gas bubbles. Due to the high complexity of the system, high performance computing is necessary to simulate the optimal geometry of the electrolyzer for flow control and gas extraction efficiency. Geometry optimization will be carried out by fluid dynamics simulation at UPPMAX. The simulation will be supported by performance assessment of the electrolyzer manufactured by resin 3D printing. NEW. This continuation proposal aims to ask for more computational power since a more complex element has been recently added to the computed system (a foam electrode) which requires a substantial increase in resources.
