Ryan O'Hayre, professor of metallurgical and materials engineering at Colorado School of Mines, was recently featured in an article in Science about a new breakthrough in the development of a midrange-temperature fuel cell that can run "warm enough for reactions to proceed quickly, but cool enough to allow them to be built from cheaper metals." From the article: O’Hayre says the new work is “a great contribution,” and calls the performance “impressive.” But he notes that there are still a few issues that need to be solved before these devices are ready for market. For starters, the current ....
