Preparation and research on poisoning resistant Zr-Co based hydrogen storage alloys

At present, all hydrogen storage alloys are poisoned by hydrogen mixed with CO, CO2, etc, which decreases the hydrogen storage property sharply. Zr-Co based hydrogen storage alloys with good poisoning resistance were prepared by alloying, fluorinating, and electroless plating. The experiment results show that the poisoning resistance of the Zr-Co based alloy was improved remarkably after the treatments. The poisoning resistance mechanism of the Zr-Co based hydrogen storage alloys was analyzed.
