The hydrogenation properties of La2Ni9CoAlx (x = 0.2, 0.3 and 0.4) non-stoichiometric alloys, in terms of their discharge capacity, the H2O/H2 exchange current density, hydrogen diffusivity and high rate dischargeability have been studied. The electrochemical tests have been carried out using chronopotentiometric and chronoamperometric methods. Electrochemical hydrogenation experiments at –185/+185...
W pracy dokonano elektrochemicznej charakterystyki stopów typu LaNi3,6(Co,Mn,Al)1,2In0,2 w środowisku 6M KOH z zastosowaniem galwanostatycznych pomiarów ładowania/rozładowania. Podstawianie Co, Mn lub Al indem w badanych stopach prowadzi do obniżenia zarówno gęstości prądu wymiany układu H2O/H2, jak i pojemności prądowej elektrod.
