DECEMBER 15, 2020
Scientists are studying transition metals such as iron as a promising alternative to platinum, but they have found that they quickly degrade in the acidic PEM fuel cell environment. Along with PNNL, researchers from Washington University in St. Previous studies had shown that cobalt is far less active than iron-based catalysts.
