Extrinsic testing of intermetallic hydrides

77 Hydrogen absorption as a function of time showing iosses after extrinsicaiiy cyciing with mercaptan (CH3SH) and NH3 gas impurities in H2. From Sandrock and Goodeii [141]. [Pg.342]

Tests on ppm levels of oxygen in hydrogen revealed significant loss in capacity due to oxidation and generally this effect is irreversible [141], [Pg.343]

2 Cycling test and response to oxygen as a minor impurity degradation behavior of AB5 hydrides [Pg.343]

Alloy surface poisoning with gaseous impurities in hydrogen has a profound effect on the hydriding properties and is highly dependent on the surface structure of the alloys or compounds [144] thus surface poisoning or contamination of metal hydrides is a very important research issue. Surface [Pg.343]

18 Extrinsic cyclic response of (a) Feo.85Mno.15Ti, 0.5 (hydrogen cycle at 25 °C, 69 634 - 69kPa) and (b) LaNis (0.5 hour cycle at [Pg.344]
