[en] The hydriding properties of Nb--Pd and Nb--Rh alloys were investigated. Results show that hydrogen uptake under retention of the body centered cubic structure, characteristic of VB and VIB metals, can raise T/sub c/. This is the case for both the original Nb₀.₈Pd₀.₂H₀.₃₉ as well as Nb₀.₈Rh₀.₂H₀.₁₀. The situation is less clear in the case of the aged hydride of Nb₀.₈Pd₀.₂. So far hydrogen take up either in Nb as well as compounds such as Nb₃Sn has been proven to be deleterious to superconductivity. The increases of T/sub c/ upon hydriding of Nb--Pd and Nb--Rh alloys can, among other factors, be explained in a straightforward fashion on the basis of lattice parameter. Alloying Nb with Rh decreases the lattice parameter of Nb as well as T/sub c/. Hydriding increases the lattice parameters again. The concomitant increase in T/sub c/ should then not be surprising as it reestablishes the original spacial situation. A similar situation holds concerning straightforward electron rules. However, beyond simple spatial and electronic arguments there will certainly be some electronic rearrangements and modifications in bonding which will have a decisive influence on superconductivity. In fact a relation can be expected to the respectable superconducting transition temperatures found in a variety of metastable compounds between Nb and noble metals at relatively high Nb concentrations. Results of the study open the possibility of achieving high values of T/sub c/ by modifying lattice parameters and electronic structure via the introduction of hydrogen
