摘要
A calcium metaphosphate glass-derived hydrogel shows high electrical conductivities of about 1 mS/cm around room temperature. Potentiometric hydrogen gas sensors using the hydrogel showed good Nernstian response to hydrogen gas concentration difference generated between detective and reference electrodes. The proton transport number of the hydrogel was estimated to be almost 1; no contribution of Ca2+ and OH-ions in the hydrogel was shown. The evaluation of amperometric hydrogen gas sensors showed that limiting currents vary with hydrogen gas flow rates.
