PERFORMANCE OF AB, ALLOYS FOR HYDROGEN STORAGE AND HYDRIDE ELECTRODES
Two types of hydride electxodes are potential candidates to replace the Cd elecsode in NilCd batteries, One is of the A type where A is a rare earth metal or mixture thereof, and B is the transition metal. The other is commonly referred to as A type. A , type alloys with partial substitution of the B element in A type hydride material (Ovonic) with Co, Mn, Al, and Fe were studied (A compo...
متن کاملSuperior hydrogen storage in high entropy alloys
Metal hydrides (MHx) provide a promising solution for the requirement to store large amounts of hydrogen in a future hydrogen-based energy system. This requires the design of alloys which allow for a very high H/M ratio. Transition metal hydrides typically have a maximum H/M ratio of 2 and higher ratios can only be obtained in alloys based on rare-earth elements. In this study we demonstrate, f...

متن کاملNanocrystalline hydrogen storage alloys for rechargeable batteries
AB -type intermetallic compounds were prepared by the melt spinning method. Structure analysis was carried out by X-ray 5 diffractometry, SEM and high resolution electron microscopy. The hydrogen storage capacity was determined by isothermic mass controlled absorption of hydrogen and by electrochemical charge /discharge cycles. A variation of the preparation parameters showed that a nanocrystal...
متن کاملHydrogen Purity Analysis by FTIR
PROBLEM Historically, hydrogen has been employed in a variety of industrial chemical processes. Typically, the purity requirements for this hydrogen have tolerated contaminant levels ranging from ppm to low percentages, depending upon the application. The use of hydrogen has now expanded into novel applications such as alternative fuel for use in transportation and stationary electrical generat...
