A downscaling visible SPE electrolytic cell model is used to study the orientation influence on the two-phase flow patterns inside the cathode flow field and its electrical performance. The results show that the two-phase flow patterns differ obviously with each other at different orientations, but much slight change of the electrical performance is observed. Increasing the electrolytic current will lead to elongated bubbles inside the cathode flow field which are formed by the coalescence of small bubbles. However, the electrical performance doesn't exhibit any dependence on the orientation. Thus, in the studied parameter range, the downscaling visible SPE electrolytic cell model used in the study can realize the gravity-independence of its electrical performance.
