Fuel cell

To operate efficiently, fuel cell stacks need precisely controlled air and hydrogen flow - a task ideally suited for our TVS technology. Fuel cells are composed of proton exchange membranes layered between a positive electrode (cathode) and a negative electrode (anode). Hydrogen is introduced to the anode, and oxygen from the surrounding air is directed to the cathode. Hydrogen molecules then break into protons and electrons due to an electrochemical reaction in the fuel cell catalyst, enabling the protons to travel through the membrane to the cathode.

The number of layers of proton exchange membranes dictates the amount of power each individual stack can produce, which subsequently means the more stacks a vehicle has the more power it produces.

The TVS fuel cell blower is covered by a housing and directly mounted to an electric motor, which operates in a range of 300 – 450 volts direct current and has no pulley or front cover. The electric motor can be calibrated to operate at fewer than 14,000 revolutions per minute. 

The technology is also scalable across a broad range of pump displacements and can be adapted to fit an individual customer’s specifications.  Light-duty automotive applications using up to a 75kW fuel cell module are well-suited for the TVS R340 model. For medium-duty automotive and commercial bus (coach) applications with up to a 150kW fuel cell module, the TVS R410 model is the best fit.
