transient three-dimensional simulation of a metal hydride hydrogen storage tank interconnected to a pem fuel cell by heat pipes

Pemfc heat generation was utilized to desorb hydrogen from a lani5 fi lled mh– hydrogen storage tank. heat pipes were used to transfer heat from the fc to the mh- tank. the study was conducted using cfd simulation. results showed that the increase of initial pressure of the mh tank and the cooling temperature of 303 k led to a rise in the hydrogen adsorption performance.after 4000 s in the desorption stage, 5.39 g of hydrogen was purged from the hydride tank. additionally, results demonstrated that a total hydrogen discharge rate of 0.304 slpm was achieved only at the expense of 7.36 w of the total 23.43 w generated heat in the fuel cell. furthermore, the hydrogen desorption fl ow rate gained 45% for the presented geometry compared to a similar system. moreover, a very good agreement was found between the present work simulation results and the literature data.
