| Abstract: | A study has been made of electrode materials based on intermetallic compounds (IMC) of the CeNi3CeCo3 series and a polymeric binding material, polytetrafluoroethylene (PTFE).It was shown that the nature of the electrode material interaction with hydrogen is similar to that of an individual IMC. The dissociation pressures of the hydride phases of CeNi3, CeNi2Co and CeNiCo2 at 293–333 K were established, as well as the main thermodynamic constants (δH, δS) characterizing the invariant equilibrium trihydrides ⤦ monohydrides in the investigated systems. Using electrochemical extraction, the formal hydrogen diffusion coefficients in IMCs and PTFE-based materials were evaluated. A study was made of the electrocatalytic activity of IMC-based materials of the CeNi3CeCo3 series in hydrogen-evolution reactions in alkaline solution. |
