    Abstract
  • Based on the study of proton exchange membrane fuel cell (PEMFC) and heat driven cooling technologies,an extravehicular spacesuit life-support system resulting from cooling-heat-power integration was presented.A typical case was calculated using the thermodynamic analysis theories and cooling-heat-power integration methods on the basis of mathematics of metal hydrogen storage,PEMFC,heat driven cooling system and radiation cooling device.The influence of the core components on the performance of the integration system was deeply analyzed.Compared with the typical spacesuit life-supported system based on cool,heat,power systems separated from each other,this system only consumes 84.6g of hydrogen without loss of working materials,and the energy efficiency is as high as 85.29%. This combined system has a greater advantage in the loss of working materials and energy efficiency.
