Webthe degradation rates of HT-PEM fuel cells are higher at the moment [1,2]. Nevertheless, HT-PEM fuel cells are steadily improving [3–5] as shown by Søndergaard et al. [6] with ultra-low degradation rates of 1.4 V/h and are on the rise, as their higher CO tolerance represents a signiﬁcant advantage over the LT-PEM fuel cells [7,8]. WebBASF offers a membrane electrode assembly (MEA) for high-temperature proton exchange membrane (HT-PEM) fuel cells and other relevant applications. This MEA operates at temperatures between 120 and 180 °C and can tolerate large concentrations of carbon monoxide as well as being able to run independently of humidification. download us against the world westlife
