摘要：

In this study, we developed a thermochemical technique to compress hydrogen gas up to more than 80 MPa. The results showed that Ti1.1CrMn alloys can generate a hydrogen pressure of 82 MPa upon being heated to similar to 200 degrees C. In order to evaluate the hydrogen absorption and desorption properties of the Ti1.1CrMn alloy at elevated temperatures, its pressure-composition (PC) isotherms were measured at 100, 140, and 180 degrees C. To examine the durability of the alloy, hydrogen compression cycle tests were performed at pressures ranging from 14 to 80 MPa by heating the alloy from 35 to 200 degrees C. In order to determine the temperature required for achieving the dissociation pressure of 82 MPa, we generated an isobar plot based on the PC isothermal measurements.
