Abstract
The activation and anti-poisoning characteristics of LmNi4.8Al0.2LmNi4.8Al0.2 hydrogen storage alloy are investigated. The incubation period of LmNi4.8Al0.2LmNi4.8Al0.2 ranges from about 8 h to just a few minutes with activation temperatures of 20 and 80∘C, respectively. Poisoning effects become more problematic with a higher concentration of CO and a greater number of absorption/desorption cycles. The poisoning can be effectively inhibited by raising the temperature during hydrogen absorption/desorption. The poisoning by H2SH2S is less than that of CO. The poisoned LmNi4.8Al0.2LmNi4.8Al0.2 alloy can be successfully reactivated by purging with high purity hydrogen gas.
