NanoDynamics Energy Awarded $2.4M For Development of 400-Watt SOFC

NanoDynamics Energy, Inc. has received a 15-month, $2.4 million contract from the US Department of Energy (DOE) for the development of a 400-watt solid oxide fuel cell (SOFC). The SOFC will be designed to operate on a variety of fuels, including hydrogen and methane gas.

The contract continues funding of a project begun in 2006 with the DOE’s Biomass program, under which NanoDynamics Energy developed a process to fabricate a single tubular cell capable of generating in excess of 20 watts. These cells were then tested and assessed for performance on a variety of fuels, including hydrogen, methane and biogas fuels.

As off-gas from waste treatment plants can vary widely in composition, and is subsequently considered a fairly low-quality fuel source, we tested the performance of our cells on a variety of gas compositions and found that across the board they could maintain relatively stable and efficient performance.

These tests helped further demonstrate the feasibility of using low-quality fuels in SOFCs, and allowed us to advance our initial single-cell success into development of a small three-cell stack capable of operating on hydrogen, waste gas and propane. This stack produced more than a 60-watt output on each of the fuels tested, and further underscored the inherent real-world advantages of SOFC technology.

Runs on methane/propane, generates 400 watts.

Could be good for an electric bike.

Now, I wonder how much they will cost?

Probably, not too good for an electronic bike. If it's based on their current 60C cell it would weigh more than 50 pounds (not including fuel), require 20 minutes for the stack to startup, and be quite large. Of course, it may not be based on existing technology. It would be nice to know what specs were specified for the $2.4M project.

Maybe not electric bicycles, but this may fit well in a co-generating water heater.

Someone might scale it up some day and build a 4000 watt device that could be used for co-generation of home heating, hot water and electricity. That would get good use out of every therm of natural gas consumed in the home.
