Abstract
The thermal, mechanical and electrochemical character of sulfonated polyetheretherketone (PEEK-S), including fuel cell tests in hydrogen/oxygen and hydrogen/air are described. Results show that in thermogravimetric analysis PEEK-S membranes lose water up to 150 degrees C and sulfonic acid groups degrade at about 240 degrees C. Thermomechanical analysis of a PEEK-S membrane of 60 micrometre in thickness and equivalent weight of 625 g/mole showed membrane shrinkage of 1.5 per cent up to 140 degrees C., followed by reversible elongation of 0.6 per cent up to 180 degrees C. Conductivity on non-reinforced and on woven-polymer reinforced PEEK-S was reported as a function of temperature and relative humidity and was similar to that of Nafion{sup R}-117. At 100 degrees C and 100 per cent relative humidity the conductivity of PEEK-S was 2-5.10{sub 2} Scm{sub 1}, increasing to 0.11 Scm{sub 1} at 150 degrees C. Polarisation characteristics of 18 micrometre thickness at temperatures up to 110 degrees C under identical pressure conditions with humidified pure hydrogen and either humidified synthetic air or oxygen were compared, and results of fuel cell tests on composite, reinforced membranes were reported. On comparison with Nafion{sup R}-115, no differences in the electrical properties of PEEK-S were noted as result
