Figure 1. Characterization of electrolyte and electrode ionomer materials.

Figure 1

a) SEM images of the SIPO-PTFE composite membrane. b) Temperature dependence of proton conductivity for the SIPO, SAPO, and FTPO-PTFE composite membranes, and 85% and 105% H3PO4. c) CV profiles for the capacitors with the SIPO, SAPO, and FTPO-PTFE composite membranes, and 85% H3PO4 electrolyte at 200°C, where 105% H3PO4 was used as the electrode ionomer. d) CV profiles for the capacitors with the SAPO, 85% and 105% H3PO4 ionomers at 200°C, where the SAPO-PTFE composite membrane was used as the electrolyte.
