WATT Fuel Cell advances efficiency in fuel cells

WATT Fuel Cell has announced a technological advancement that dramatically increases the efficiency of its fuel cells and reduces their already minimal CO2 emissions.

WATT achieved the breakthrough efficiency gain by employing a new Catalytic Partial Oxidation (CPOX) fuel processing technology combined with its innovative Additive Manufacturing Process (AMP), a 3D printing process that enables them to tailor the composition and microstructure of their Solid Oxide Fuel Cells (SOFCs).

One of WATT’s biggest advantages is developing and manufacturing. This level of vertical integration enables us to rapidly develop and implement innovative ideas and stay at the cutting edge of SOFC technology.

The technology was already outperforming other similar fuel cell system efficiencies by 10-15%. This advancement continues to extend that advantage. The development results from an innovative CPOX reforming process, leading to >50% efficiency in WATT’s SOFCs, surpassing competitors by 10%.

CPOX reforming, the combination of air and fuel to produce hydrogen, is used for its simplicity, ability to cycle, and lower price point. The process traditionally yields a lower efficiency than steam reforming, which involves processing fuel with steam rather than air. WATT’s new technology levels the playing field, delivering performance comparable to steam-based systems without the disadvantages of the additional components and costs.

A case study analyzing the impacts of the increased efficiency for the deployment of the ImperiumR residential fuel cell systems by a mid-Atlantic gas utility indicates 40% avoided CO2 emissions.

Rich Romer, WATT’s CEO, said, “The firm’s ongoing work with Peoples Gas over the past three years, and now EQT’s engagement, will enable us to enter the residential market and harvest opportunities we have been pursuing for industrial/business fuel cell commercialization.”
