Line Plot from Scientific Research

IEC performed on a 10 mmol dm–3(10 mM) H3PO3electrolyte that has been aged for a specific duration (τ) at 70 C [for panels (B) and (C)] or 25 C [for panel (D)]. In panel (B), no Pt/C catalysts were dispersed in the electrolyte before aging, while in panels (C) and (D), 50 mg of Pt/C catalysts (40 wt % Pt) were dispersed before aging. Note that the eluent solution in panels (B) and (C) was 20 mmol dm–3KOH, while the eluent in panel (D) was 15 mmol dm–3KOH; therefore, a different retention time is observed for H3PO3/H3PO4species in panels (B) and (C) compared to panel (D).
