Fuel Cell FAQs
Learn more about our patented microtubular fuel cell technology and find out how it can enhance your energy system.
What makes your products reliable?
Unlike all other types of fuel cells, our proprietary microtubular design offers built-in redundancy. Power controls on the stack allow individual fuel cells to fail, so the system will never go down even if a single tube falters. Our products offer peace of mind that your load will be powered no matter what.
Do your systems operate in extreme cold?
Other technologies are vulnerable to failure in freezing environments: Thermoelectric generators (TEG) produce liquid water during the reaction, and proton exchange membrane fuel cells (PEM) or direct methanol fuel cells (DMFC) must be kept moist. However, our Solid Oxide Fuel Cells are engineered to store, start and operate in temperatures from -40°C to 50°C. They produce no liquid water and are constructed of heat-resistant ceramic tubes that will not freeze. This means you’ll never have downtimes caused by cold weather.
What’s your fuel efficiency?
Our systems operate at 20% fuel efficiency, which is significantly greater than other technologies like thermoelectric generators (TEGs) or gas/diesel generators. Plus, our systems run on propane, which is cleaner than diesel and bypasses the carbon inefficiencies of converting hydrogen into power. When decarbonization is crucial to your business, our SOFCs are the only option.
Can a 250W system operate at a lower output?
Yes. And operating at a lower output would extend the system's run hours but not its cycles. The degradation during cycles is accumulated during the warming and cooling period, not how many times it cycles on and off.
Do your products integrate with hybrid power systems?
Yes. Our products integrate seamlessly with A/C grid, generator, battery, DC-DC, wind or solar technologies — even serving as the rectifier if necessary — or can be included in new installations. To minimize lifecycle cost, we provide targeted engineering support for each application.
How long can a 250W system run on a 20-lb propane tank?
One 20-pound BBQ-sized tank of propane from your local gas station can keep one of our Solid Oxide Fuel Cell systems running for 80 hours. This gives you plenty of time to schedule a site visit to switch out the propane tanks before the system runs out of fuel.
