The fuel cell is regarded as one of the key devices for reducing greenhouse gas emissions and achieving carbon neutrality. Neutron imaging is anticipated to contribute to fuel cell study especially on its water management by non-destructive observation of generated water inside the cell during the operation. In addition, the operando imaging using the neutron beam is a unique technique to provide direct information about this requirement because of its high transmission ability and the large field of view. We have developed an operation system to drive full-sized fuel cell for automotive which can be used inside the neutron imaging beamline RADEN in J-PARC MLF. It consists of gas supply units for the anode and the cathode lines, which control temperature, humidity, flow rate of each gas independently, back pressure units to control gas pressure in each line, and a load unit to control the power generation.
