3.3. Parr Reactor<br />
Samples of LaNi 5 with 0.74, 1.35 and 3.38% Al were tested in the Parr reactor.<br />
After the activation procedure, the reactor was pressurized with H 2 sealed. Pressure drop<br />
was monitored and the percent hydrogen absorbed was calculated using the ideal gas law.<br />
