Abstract Fuel cell (FC) propulsion for small (MTOW From the results obtained, the operation of the CPV array and the CPV inverter connected to the electrolyser were both satisfactory, and no significant operational issues were observed. The overall energy efficiency of the CPV-inverter-electrolyser system was below 40%, mainly due to the excessively long start-up periods during which the electrolyser is not producing hydrogen, the slow dynamic response due to regular pressurization and depressurization cycles of the electrolyser and the excessive power consumption of the electrolyser auxiliaries. It is expected that if some optimization is carried out, mainly related to the control system of the electrolyser, the overall energy efficiency should increase and the dynamic response of the electrolyser can be improved.
