Improved quality in hydrogen tanks, blowers, pumps & compressors
In fuel cell testing, material research of hydogen tanks or of components such as injection valves, compressors (air system), blowers or pumps on the cooling side, Polytec Laser Doppler vibrometers assist in thourough vibration analysis. Polytec’s range of non-contact vibration measurement sensors help validate the FE model, visualize the operational deflection shape (ODS) of both the single component or assembly, can identify components with highest contribution to fuel cell vibration and thus noise or for NVH testing (noise, vibration and harshness).
Measure and validate your H2 components
Why laser vibrometers for H2 component testing
- Non-contact: Non-reactive, even in hard-to-reach areas
- Auto focus: Reliable measurement results at short and long distances
- Reliable: Unaffected by ambient noise
- High precision: Valid data detecting even small differences
Hydrogen Fuel Cell Vehicles (HFCV) on the rise
However, one major problem that electric vehicles have to overcome is the limited range one can drive before the need to recharge the BEV batteries. This is not only a problem with passenger BEV’s but also even more with commercial vehicles such as Trucks and Buses where a long travel range is needed.
The automotive industry is looking for solutions how to extend the range of carbon neutral vehicles. In contrast to BEV the hydrogen-based fuel cell (FC) technology overcomes the range problem. This is because larger hydrogen fuel tanks can store more energy and on top, the refueling process is faster compared to a battery recharge. Thus, countries not only in Asia are heavily funding the fuel cell technology and fuel cell infrastructure. FC technology acceptance especially in larger commercial vehicles such as trucks and buses is growing.
Quiet & reliable fuel cells: NVH testing of hydrogen technology
To become fully accepted in vehicles the fuel cell technology has to be reliable, safe and comfortable. Directly related to comfort is the noise level of the vehicle which should be as low as possible. Thus, vehicle manufacturers need to ensure that each system component used in the vehicle is not dominating the overall noise level by tonal noise.
