In this work, a hydrogen permeation evaluation system using a cylindrical Pd cell was constructed to evaluate the hydrogen permeation properties of Pd and Pd-Ag alloys. A combined gas and electrochemical system was fabricated, and hydrogen permeation behavior was evaluated under various temperature conditions by controlling the temperature of the solution in contact with the entire cylinder. Hydrogen permeation experiments were also conducted using electrochemical methods to evaluate the temperature and concentration dependence of the diffusion coefficient.
