The rate at which rare-earth intermetallic compounds absorb and desorb hydrogen can be controlled by ''poisoning'' the catalytic reaction, H/sub 2/=2H. Specimens treated with SO/sub 2/, a well-known catalytic ''poison'', are prevented from absorbing hydrogen for extended periods. More surprisingly, SO/sub 2/ treatment after hydriding prevents hydrogen desorption by specimens for weeks. The applications of this process to energy storage are numerous. (AIP)
