METHOD FOR PRODUCING CATALYST INK - A simplified explanation of the abstract
This abstract first appeared for US patent application 18530548 titled 'METHOD FOR PRODUCING CATALYST INK
The patent application describes a method for producing a catalyst ink for fuel cells, which includes a catalyst, a carbon support, an ionomer, a solvent, and a cation additive.
- The catalyst ink contains catalyst supported on carbon support particles with a particle size D90 of less than 3 μm.
- The peel strength of the catalyst layer formed by the ink on a substrate is less than 3 N/m.
- The weight per unit area of the cation additive in the catalyst ink applied to the substrate is between 2.1 μg/cm² and 3.3 μg/cm².
Potential Applications: - This technology can be used in the production of fuel cells for various applications, including automotive, portable electronics, and stationary power generation.
Problems Solved: - The method addresses the challenge of achieving a strong bond between the catalyst layer and the substrate in fuel cell applications. - It also ensures uniform distribution of the catalyst and additives in the ink for optimal performance.
Benefits: - Improved adhesion and durability of catalyst layers in fuel cells. - Enhanced efficiency and performance of fuel cell systems. - Cost-effective production of catalyst inks for large-scale applications.
Commercial Applications: - The technology can be utilized by fuel cell manufacturers to enhance the performance and reliability of their products, leading to increased market competitiveness and customer satisfaction.
Questions about Catalyst Ink for Fuel Cells: 1. How does the particle size of the carbon support particles impact the performance of the catalyst ink? 2. What are the key factors influencing the peel strength of the catalyst layer in fuel cell applications?
Original Abstract Submitted
A method for producing a catalyst ink for fuel cells, wherein the method comprises obtaining the catalyst ink; wherein the catalyst ink comprises a catalyst, a carbon support, an ionomer, a solvent and a cation additive; wherein the catalyst is supported on the carbon support; wherein the carbon support is carbon support particles; wherein a particle size D90 of the carbon support particles in the catalyst ink is less than 3 μm; wherein, when a catalyst layer is formed by applying the catalyst ink to a substrate, a peel strength of the catalyst layer from the substrate is less than 3 N/m; and wherein a weight per unit area of the cation additive in the catalyst ink applied to the substrate, is 2.1 μg/cmor more and 3.3 μg/cmor less.
