Fuel cells have long attracted interest because of their low impact on the environment and potential for energy efficiency. Unfortunately, technical problems and high costs have prevented this potential from being realized. Some of the costs are directly related to the traditional use of platinum as a catalyst. Over the past decade, researchers and entrepreneurs have brought down costs considerably and increased the reliability of fuel cells. The use of nickel both as a metal and an oxide has been an important part of these efforts.
