How to improve fuel cell production and development by measuring and adjusting the physical and chemical properties of active components
To achieve the best fuel cell performance you need to understand the physicochemical properties of your active components and engineer them to your advantage. Anton Paar has the technology you need to optimize each component.
Ensuring the right catalytic activity is key to the excellent performance of the fuel cell.
To build fuel cells which maintain their activity well, you can assess the active metal area and the dispersion using one of Anton Paar’s chemisorption devices. Optimizing these physicochemical properties brings you a significant cost benefit as noble metals can be implemented more efficiently before cell assembly.
To determine the final concentration of these noble metals, elemental analysis has to be performed which is only possible after adequate sample preparation with microwave-assisted acid digestion. Research into novel materials for fuel cells, in particular catalysts, is facilitated and accelerated by microwave synthesis.
To improve catalytic activity you can evaluate and adjust the particle size of the catalyst material using a particle analyzer.
To improve the catalyst support you can minimize the variability between batches of carbon before they are used for impregnation/deposition. Anton Paar’s gas sorption analyzers deliver a detailed assessment of the pore size and surface area distributions and you can use this information to achieve a consistent surface area and pore size of the nanoporous carbon.
Modifying the surface of carbon nanotubes can also improve catalytic performance by facilitating the proton transfer through the catalyst layer. These modifications can be done based on evaluation of the zeta potential of the surfaces with Anton Paar’s electrokinetic analyzer.
The gas diffusion layer can be improved by optimizing fluid permeability and controlling flooding. To evaluate the gas permeability, water management, and ohmic behavior before cell assembly, you can perform pore size distribution measurements and use the results to make adjustments for better performance.
To ensure consistent and sufficient fluid transport before cell assembly and control flooding, use a vapor sorption analyzer to make hydrophobicity/hydrophilicity measurements and determine the best gas diffusion layer composition.
