A device known as an air cleaner, purifies the air in a space to raise the standard of indoor air. These products are frequently marketed as being helpful for people with allergies and asthma, as well as minimising or eliminating secondhand smoking.
The design of the cathode air cleaner element depends on finding the best possible balance between pressure drop and volumetric adsorption efficiency in all cathode air cleaners.
The likelihood of adsorption increases and the pressure drop also increases when the hazardous gas passes through multiple layers of activated carbon.
The mass of the absorber determines the cathode air filter elements, and when the activated carbons are fully loaded or the dangerous gas begins to leak through, the filter needs to be changed.
By poisoning the catalyst, obstructing the channels, and degrading the membrane, airborne particles and gases can harm the fuel cell stack.
These impurities are shielded from the fuel cell stacks by the cathode air filter. The stack can receive clean air and continues to function thanks to the combination of adsorption and filtration.
The Global cathode air cleaner market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Commercial vehicle cathode air cleaner system by MANN+HUMMEL.
The development of an original sensor array is being supported by the German Federal Ministry for Digital and Transport by a group led by MANN+HUMMEL.
We are currently witnessing various driving systems fighting to replace the combustion engine as a result of the transformation occurring in the transportation industry.
Performance, operational time, sustainability, and cost are the main considerations in this case. When it comes to personal mobility, industry and politics are mostly focused on battery-powered electric cars, but there is a growing interest in the use of fuel cells for commercial vehicles.
The performance/lifetime ratio will be improved by innovative air filter sensor technology from MANN+HUMMEL, which has its eyes on the Chinese market in particular.
Principal Expert Electric Mobility at MANN+HUMMEL says that factors like the cleanliness of the cathode air in the catalyst might affect the lifespan of a PEM fuel cell.
“The platinum-coated cathode reduces oxygen, but gases with nitrogen or sulphur bind to the platinum particles. They obstruct the catalyst as a result, which lowers the fuel cell’s efficiency.
As part of a consortium, MANN+HUMMEL is currently working with two other partners to create a sensor array for the cathode path in order to allow usage-based maintenance.
This will show when the used activated carbon has gotten saturated and dangerous gases are starting to get through the filter.
A penetration sensor array based on gas-sensitive surfaces for use in automobiles under dynamic environmental conditions is being developed as part of this project by the Institute for Energy and Environmental Technology (IUTA) in Duisburg, together with a smart signal processing system tailored to this.
The Research Institute for Precious Metals and Metal Chemistry (fem Forschungsinstitut Edelmetalle + Metallchemie) in the German town of Schwäbisch Gmünd is providing the sensor layers, which will react sensitively and selectively to specific toxic chemicals and mixtures of harmful gases.
At MANN+HUMMEL, they are concentrating on integrating the array into the cathode air path in addition to designing cathode air cleaner media specifically adapted to the profiles of hazardous gases.
