The phase transition from supercooled water to ice is closely related to the electrochemical performance and lifetime of an energy device at sub-zero temperatures. Fuel cells for automotive face this issue because they are frequently started and stopped under sub-zero conditions. In this study, we developed an operando neutron imaging system to visualise the water distribution inside an automotive single cell simulating a fuel cell stack during cold starts.
