A methane fuel cell that operates at lower temperatures

By Scott Jenkins |

Existing methane fuel cells typically require high (750–800°C) temperatures to activate methane in a separate methane reformer that creates hydrogen gas. Now researchers at the Georgia Institute of Technology (Georgia Tech; Atlanta; www.gatech.edu) have developed a solid oxide fuel cell (SOFC) design that eliminates the need for a methane reformer and requires temperatures of only 500°C. The cost savings enabled by the lower-temperature operation could make this type of fuel cell, which uses no platinum, commercially viable for several applications, including distributed power generation and automobile engines. “In our fuel cell, we integrated thermal catalysis and electrocatalysis at 500°C,” explains Meilin Liu, Georgia Tech professor and lead researcher. “Methane is first reformed to CO and H2 within the fuel cell, and then the H2 and CO are electrochemically oxidized to H2O and CO2 on the electrode.” The lower-temperature fuel cell would allow ordinary stainless steel, rather than exotic materials, to be used for the interconnectors that link the cells into a stack. “Above 750°C, no metal can withstand the temperature without oxidation,” Liu says, so the materials needed are “expensive and fragile, and would…
