Nonprecious‐Metal Catalysts for Low‐Cost Fuel Cells

Within reach: Newly developed nonprecious-metal catalysts can be used to produce inexpensive hydrogen fuel cells with performances approaching those of platinum-based systems. For example, the best non-Pt catalyst was prepared from a metal–organic framework consisting of zeolitic ZnII imidazolate which served as the host for the Fe and N precursors of the catalyst. The plot shows the volumetric current densities of the best non-Pt catalysts and the target value set by the U.S. DOE at 0.8 V).
