Neutron radiography is an effective water diagnostic tool for fuel cells. We continuously observed water behavior in a small type fuel cell under operation by high performance neutron radiography system using Neutron image intensifier. Water generated in the cell was initially accumulated in region of MEA and GDL, extending to a channel gradually. We will report and discuss about relationship between voltage drop and the water behavior in presentation.
