Experimental analysis on the collaborative operation of fuel cell and adsorption chiller composite system under multi-operating conditions

•Establish an experimental platform of PEMFC and adsorption chiller composite system.•Steady-state performance of the system under different electric powers is studied.•The maximum error of the simulation results is 3.02 % at the rated power.•Dynamic performance of the system under low and high-power conditions is studied.•Cooling power is reduced by 20.76 % when the heating power of the chiller is halved.
