Multi-physics modeling of cold plasma reformers

Abstract

Hydrogen, as a clean energy carrier, reduces carbon emissions. With the fast development of fuel cell vehicles, the demand for hydrogen is increasing. The mainstream production of hydrogen is through steam reforming, requiring high temperature and large scale facilities. The distribution is through high pressure gas cylinders. The installation of hydrogen cylinders in households without professional handling can be dangerous. Compared to steam reforming, the pulsed cold plasma reforming method is a promising way to generate hydrogen in small scale stationary and mobile platforms. In this thesis, a Multiphysics model, analysis, and study of a pulsed cold plasma reforming chamber are presented. Results in terms of electromagnetic field, thermal analysis, and electrical currents are shown both via simulation and experimentally in order to validate the accuracy of the model. This research will generate new opportunities for the optimization process of design of cold plasma chambers for the hydrogen generation process which can in turn introduce substantial savings in costs and time during the research and development phase of this type of products.
