The feasibility test was performed to check the possibility of 2-phase flow visualization and water distribution at inside the PEMFC using neutron radiography image technique. It was composed using water and pressured air. From the image, several 2-phase flow patterns were discovered and water fraction was estimated by the reference specimen and image analysis.
