| Abstract: | In this paper,the problem of alloy pulverization during the operation of hydrogen oxygen fuel cell is presented,and the hydrogen storage mechanism and technical characteristics of ferrotitanium alloy is described in detail.Then,the reason and influence of hydrogen storage alloy pulverization are analyzed,and meanwhile,the solution is put forward.By adding hydrogen gas washing device such as water washing,the possible particulate matter in hydrogen charging can be eliminated.In the long run,doping modification of alloy composition can improve the toughness of hydrogen storage alloy and reduce the cracking probability of material.This could be the direction for the future work. |
