I-6 – High-temperature proton-conducting polymer membranes



Organizers: Piercarlo Mustarelli (University of Pavia), Werner Lehnert (Forschungszentrum Juelich), Andrew Herring (Colorado School of Mines).

High-temperature polymer electrolyte fuel cells are beneficial for stationary applications as well as for applications as auxiliary power units in trucks, trains and airplanes. At present, however, the cost and performance of fuel cells operating above 100°C are not yet satisfactory enough to envisage a widespread alternative to conventional technologies. In this frame, the most recent research efforts have been focused on the development of both catalysts and proton-conducting membranes. Concerning the former topic, the major issues are: (i) minimizing the overall Pt content in the catalysts; (ii) improving sluggish kinetics of the ORR at the cathode. Concerning the latter one, the attention is chiefly devoted to: (i) maximizing membrane durability, and (ii) increasing membrane proton conductivity without causing losses in stability.

This symposium aims at discussing the most recent developments in the field of proton-conducting, polymer-based membranes for high temperature polymer electrolyte fuel cells and related applications. In particular, it will treat, but it will be not limited to, the following topics: (i) development of new composite and blended materials with improved proton conductivity, chemical and electrochemical stability and durability; (ii) new in situ and operando characterization techniques of MEAs; (iii) multi-scale modeling (micro-, meso- and macro-scale) of isothermal and non-isothermal processes in membranes and interfaces; (iv) theoretical/experimental investigation of transport mechanisms in complex systems. The working temperature range considered in this symposium is 100-300°C. The attention will be chiefly focused on materials based on polybenzimidazole, however also other systems (pyridine-based, etc.) are welcome.


Abstracts are solicited in, but not necessarily limited to, the following areas:

In this Symposium are also welcome those contributions which cover the topics beyond the above-described areas. This is done to provide the audience with a comprehensive description of Solid State Ionics. If your contribution is difficult to host within the above areas, please do not hesitate to contact directly the Conference Chairmen at ssi21@dii.unipd.it for advice.
