“…Therefore, it is side by side through comparing the stabilized open-circuit voltage (Voc) versus state of charge (SOC) curves in the electrochemical PCT (EPCT) and gaseous phase PCT curves. [6] Noble metals like Pd and Pt [7] The EPCT method is not a new idea and had been applied in a number of MH alloy studies, including studies on AB5 [8][9][10][11], AB2-based multiphase alloys [12][13][14], Ce-Mn-Al-Ni [15], Ce-Mg-Ni-Ti-F [16], carbon nanofiber [17], and Mg2Ni [18]. In EPCT, the stabilized Voc is converted to equilibrium pressure via the Nernst Equation (1) [19]:…”

In this study we compared the electrochemical pressure-concentration-temperature (EPCT) method with the gaseous phase pressure-concentration-temperature (PCT) method and demonstrated the differences between the two. Experimentally, this was done by electrochemically charging/discharging the electrodes of four different metal hydride (MH) alloys. The results indicate that in the PCT curve is flatter with a smaller hysteresis and a higher storage capacity compared to the EPCT curve. Moreover, while the PCT curves (up to around one third of the hydrogen storage capacity) reside in between the charge and discharge EPCT curves, the rest of the PCT curves are below the EPCT curves. Finally, we demonstrated a new calibration method based on the inflection points observed in the EPCT isotherms of a physical mixture of more than one alloy. This turning point can be used to find a preset calibration point to determine the state-of-charge.
