PEFCs should not only be environmentally advantageous relative to the conventional power-generation devices that PEFC products seek to replace, they must also be on par with these devices on an economic basis to be commercially successful. Therefore, the cost and durability goals for PEFCs tend to be based on the capabilities of the incumbent technologies. For example, the U.S. Department of Energy ...
