Proton-conducting solid electrolytes are closely related to alkali ion conductors and are likely to receive increasing attention in EP applications with respect to both fundamental issues and technical applications. Both aspects are therefore illustrated in this section. 

Japanese researchers [248] have designed an apparatus for the electrochemical reduction of carbon dioxide employing ultrasound. The apparatus comprises an electrolytic cell containing C02-dissolved electrolytic solution, a porous Pt-group metal anode, a proton-conductive solid electrolyte having a porous metal cathode used as a catalyst for the electrochemical reduction of COz on one side and a second anode on the other side facing oppositely to the cathode, and an ultrasonic vibrator. C02 can be reduced effectively for a long time.

One of the current goals within the field of PEMFCs is to find a nonaqueous, proton-conducting solid electrolyte-membrane system for fuel cells. While these are not PlLs, they have similarities. Proton-exchange materials have been produced from imidazolium cations with inorganic anions, such as benzimidazole with TFSl, formed into a polymer with mai similarities to PlLs.

The same principle can also be applied to the construction of potentiometric sensors for other gases. Thus, cells with proton-conducting solid electrolytes (water-containing In-doped CaZrOa [540], cf. Section 5.6) are used to measure H activity in aluminium and hence to control the brittleness associated with hydrogen content. It is not necessary that the gas to be detected and the mobile ion refer to the same element. Let us consider a chlorine sensor based on AgCl. AgCl in contact with CI2 gas fixes a defined silver activity and cells of the type...
