Miniaturized Fuel Cell Solution
Our unique value proposition
Solid Oxide Fuel Cells (SOFCs) have many advantages: high efficiency, fuel versatility, low carbon sensitivity and long lifetime. These positive attributes nevertheless require high operation temperature that limits their application to large power solutions.
We developed a patent pending solution based on composite structure addressing main technical challenges such as scalability, thermomechanical stability, system integration, and thermal packaging at low-cost. Our innovative all-in-one solution integrates a complete SOFC system including fuel cell membrane, gas delivery and reforming, heater, and post-combustion chamber. This allows us to produce small, efficient and cost effective systems.
Our value propositions are:
Fuel flexibility: our units can operate based on several fuels including (bio)propane, hydrogen and potentially (bio)methane.
Lightweight: our unique design allows to have light and compact units, 60-80% smaller than comparable units.
High efficiency: SOFC systems allow to have overall high efficiency, up to 30-35% using propane and above 45% using hydrogen. As a reference, the efficiency of a small gasoline genset is around 10-15%.
Cost effective: the manufacturing of our products doesn’t require expensive manufacturing processes and most of the steps used are scalable.
Solid Oxide Fuel Cell (SOFC)
The fuel is continuously fed to the anode side and the oxidant (oxygen from the air) is supplied to the cathode side. There, the electrons dissociate and reduce absorbed oxygen and consequently form oxygen ions. The ions diffuse through the electrolyte and oxidize the fuel at the anode side. The product of the reaction is thus electrons plus water steam and very small carbon dioxide if carbon fuels are used.
Advantages of SOFCs
The performance of fuel cells are highly dependent on the using fuel. For example, bio-propane is among the fuels with highest energy density. In comparison to the currently used Li-batteries technology, its energy density is 40-60x higher. This means that SOFC based power systems can dramatically increase the autonomy at the same size and weight. A compact and lightweight power solution that can be easily transported or stored in any control cabinet.
Hydrogen is also a very good option even if the resulting energy density is slightly lower, about 3-6x higher than Li-batteries at 200bar. Future hydrogen storage technologies will probably improve this figure.
Moreover, fuel cell based power solutions can deliver power independently from the grid and weather conditions, which give them a clear added-value in comparison to renewable resources such as solar panels.
Unlike diesel generators fuel cells have a silent operation with minimum emissions while avoiding frequent fuel and oil refilling.
Solid oxide fuel cells are one of the most efficient fuel cell technology allowing reduced emission even when using hydrocarbons as fuel. Using propane as a fuel and considering an efficiency of 30-35%, our system induces only 600g/kWh carbon emission, which is in the same range as lithium battery system charged using grid power (500g/kWh according to EU average grid impact). The CO2 impact can be decreased further using green-hydrogen or bio fuels, potentially reaching <100g/kWh carbon emission.
