Hydrogen-storage alloys (18,19) are commercially available from several companies in the United States, Japan, and Europe. A commercial use has been developed in rechargeable nickel—metal hydride batteries which are superior to nickel—cadmium batteries by virtue of improved capacity and elimination of the toxic metal cadmium (see BATTERIES, SECONDARYCELLS-ALKALINe). Other uses are expected to develop in nonpolluting internal combustion engines and fuel cells (qv), heat pumps and refrigerators, and electric utility peak-load shaving. [Pg.300]

Those rare-earth AB -type hydrides were quickly utilized in rechargeable nickel metal hydride batteries where electrochemical hydrogen charging and discharging take place at ambient temperature. Such electrochemical hydrogen storage is reversible, when the negative hydride electrode (anode) is combined with the positive Ni electrode (cathode) in the battery cell.. [Pg.14]

Union Carbide showed the possibility of developing D-size hydrogen-nickel batteries with satisfactory performance. However, safety and cost considerations have restricted the applications of such units and the discovery of hydrogen storage alloys led to the development of the nickel-metal hydride secondary cell which was described in Chapter 6. [Pg.299]

Engineering applications such as hydrogen storage in metal hydrides, the nickel-metal hydride rechargeable battery (Ni-MH), and the proton exchange membrane fuel cell (PEMFC) are basically dependent on the surface properties and characteristics. [Pg.132]

The nickel metal hydride battery functions on the principle that some intermetallic compounds can react directly and reversibly with hydrogen to form a hydride phase. Nickel is the most common metal for hydrogen storage. The half-cell reactions are ... [Pg.1501]

A key component of the sealed nickel-metal hydride cell is the hydrogen storage metal alloy. The composition of the alloy is formulated to obtain a materi that is stable over a large number of charge-discharge cycles. Other important properties of the alloy include ... [Pg.842]

The button configuration is illustrated in Fig. 29.2b. It is similar in construction to the nickel-cadmium button cell, except that the cadmium is replaced by the hydrogen storage aUoy. [Pg.844]

Nickel-metal hydride (NiMH) cell — used in hybrid vehicles as a supplemental energy source utilizes hydrogen storage in metal alloys, has a low mass, high energy density, high current load capability, and is nontoxic (enviromnentally friendly)... [Pg.208]
