Performance estimation of dehydriding process in metal hydride hydrogen storage tank with coiled-tube heat exchanger

Various thermal management methods are widely adopted in the metal hydride (MH) system to release the thermal effect and obtain acceptable hydrogen storage performance. In this work, an axisymmetric numerical model for a simple MH system without a heat exchanger (HE) has been established and validat...
