High-temperature proton exchange benefits

As discussed in the previous sections, an increase in PEM fuel cell operating temperatures to >90 °C not only resolves or at least alleviates some LT-PEM fuel cell problems but it also provides other benefits. One of the key components when operating PEM fuel cells at high temperatures is the proton exchange membrane another is the electrocatalyst. However, the Uterature contains limited information about HT-PEM fuel cell catalysts. It is expected that high-temperature operation will pose challenges for catalyst stability, but...
