Hello All,
I am trying to calculate the loss of hydrogen gas by diffusion through the wall of acrylic container (Grade: Polymethyl Metha-Acrylate) stored at atmospheric pressure and temperature.
To explain my question further:
Actually, i am doing some research work on the cost efficient storage of hydrogen at low pressures. Due to the smaller molecular size of the hydrogen the issues like diffusivity in case of hydrogen storage is a major issue. At this time, i am using a small laboratory scale acrylic container (diameter 150 mm, height 550 mm and wall thickness 3 mm). I have done some research using Ficks law of diffusion through polymers for my calculations. I will greatly appreciate if someone could provide me with any relevant information in this regard like diffusivity coefficient for acrylic materials, fibre reinforced plastics (FRP), non metalic composite etc.
