Abstract
The activation and anti-poisoning characteristics of LmNi 4.8 Al 0.2 hydrogen storage alloy are investigated. The incubation period of LmNi 4.8 Al 0.2 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 H 2 S is less than that of CO. The poisoned LmNi 4.8 Al 0.2 alloy can be successfully reactivated by purging with high purity hydrogen gas.
