Reliable, affordable fuel cells have come not one but three steps closer to reality this week, with announcements from two research institutions regarding advances in the field. If the reported developments make their way into production, we could be seeing fuel cells that use more abundant, less expensive fuels and building materials, that are more consistent in their electricity production, and that have a lower operating temperature.
