According to foreign media reports: The TurbuGrid is a small plastic grid of approximately 16 x 16 cm that significantly improves the efficiency of air-cooled fuel cell stacks. Tests by AAU researchers show that efficiency has increased by at least 33.5%. If such a plastic grid is added to a new fuel cell stack, the resulting increase in efficiency will be even greater. Researchers say that TurbuGrid's fuel cell efficiency improvement is due to the fact that the grid adds turbulence to the air flowing into the stack channels. Turbulence has an important influence on the heat transfer occurring in the fuel cell, which is of great significance for the power density of the fuel cell. The addition of artificial turbulence in the gas stream is a fundamental change in the way to get more energy from the fuel cell stack. This is because the previous focus was on achieving higher efficiency, mainly on avoiding pressure drops rather than more efficient heat transfer. Due to the small space inside the fuel cell, it is difficult to accurately calculate and measure the temperature. Torsten Berning and his research colleagues used a computer model to combine physics experiments. The results of the model and the reality are obvious: When the plastic net is added to the battery, the efficiency and output power increase significantly. At present, air-cooled fuel cells are being used for material handling in forklifts, as an emergency power source for IT and telecommunications industries as well as small drones. Depending on how they operate, the fuel cell life is usually 5 - 6 years, but by adding the TurbuGrid to the fuel cell stack, the service life can be extended because the temperature in the battery is controlled in a more appropriate manner. The cost of an air-cooled fuel cell stack is at least $1000/kW, so besides using the TurbuGrid on a new stack, adding it to a fuel cell stack already in use is also a good choice. Aalborg University and Torsten Berning have applied for invention patents and are now seeking industrial partners interested in future cooperation. The project behind the invention, TurbuGrid, is powered by EUDP (Energy Technology Development and Demonstration Project).
