Low-temperature fuel cells with a polymer membrane electrolyte are at an exciting time in their development. State-of-the-art proton-exchange membrane fuel cells (PEMFCs) are able to achieve extremely high areal current density and high power density. Systems have been demonstrated with tens of thousands of hours of continuous lifetime. Despite this, these low-temperature fuel cells remain unable to achieve appreciable market penetration. In many cases (e.g., automotive) the main reason for limited commercial deployment is that the overall cost remains too high, and it is believed that further engineering of the existing system may not allow PEMFCs to meet government and industrial cost targets. Very similar arguments can be made for the limitations of existing low-temperature membrane-based electrolysis systems for producing H2.
