"semi-cylindrical coil as an internal heat exchanger, which significantly improved heat transfer performance. The hydrogen charging time was reduced by 59% when using the new semi-cylindrical coil compared to a traditional helical coil heat exchanger... numerical simulation of hydrogen desorption... improve absorption times... semi-cylindrical coil heat exchanger"
