Abstract
When metallic alloys are reacted to hydrogen, heat transfer of storage tank effects hydrogen storage rate and capacity. If pulsating heat pipe are used to improve heat transfer efficiency, production of hydrogen storage tank can be more simple and economical. Experiment of heat pipe was conducted by varying working fluids and heat flux. According to supply heat flux, test indicate that R-22 and R-l42b were found lower temperature difference between evaporator and condenser than R-134a and Ethanol. Thermal resistances of R-22 and R-142b were also lower than others. Using R-142b as a working fluid, heat pipe type hydrogen storage tank is tested in absorption and desorption processes.
