Fuel Cell on Continuous Duty

A planar solid oxide fuel cell at the Research Centre Jülich has exceeded the threshold of 40,000 hours of operation. This corresponds to permanent operation over the course of almost five years and constitutes a world record to date. This puts an economic use in stationary applications within reasonable reach, for instance, for providing private households with energy. The test stack from Jülich transforms hydrogen into electrical power at 64 per cent degree of efficiency. Other fuels, such as natural gas, can likewise be transformed and even at a higher degree of efficiency, as was verified during other experiments.
