LNnewpower Carbon Paper Products
On the basis of carbon fiber composite fabrication technology, LNnewpower research team learned previous experience of commercial GDL products, comprehensively considered the kinetic and thermodynamic requirement in electrochemical reaction, developed the new generation carbon paper products.
The Lnnewpower carbon paper products achieve high electrical and thermal conductivity as well as reliable mechanical support capacity. The products can effectively improve the mass transfer and diffusion of liquid-gas phase between bipolar plate flow field and catalyst layer.
The Lnnewpower always adheres to customer demand-oriented principle. Parameters of product, which include thickness, porosity, pore size distribution, hydrophilicity & hydrophobicity and so on, can be customized and adjusted. The customized products are suitable to different electrochemical equipment and complex operating condition.
More specific information about customization, please contact LNnewpower marketing department.
LNnewpower Carbon Paper Products
High Conductivity
The products possess excellent electrical conductivity and thermal conductivity, which can reduce ohmic polarization loss and increase the efficiency of electrochemical reaction.
Effective Mass Transport Management
By controlling the porosity, pore size distribution and pore structure, combining with hydrophobic or hydrophilic modification, the products gain excellent permeability and proper hydrophobicity. During the operation of electrochemical equipment, the products can facilitate the input, diffusion and output of reactants and resultants, reduce concentration loss in region with high electrochemical reaction rate.
Robust Mechanical Support
The composite structure of product provides adequate mechanical support and deformation resistance. According to requirement for assembly of different electrochemical equipment, products with proper thickness, strength, porosity and compressibility can be supplied.
Smooth Surface
The microporous layer of products possess smooth surface and low surface roughness，which have positive effect on interface between substrate and catalyst layer in membrane electrode assembly (MEA), the contact resistance between gas diffusion layer and catalyst layer is improved meanwhile. The smooth surface also fits the catalyst coated substrate (CCS) or catalyst coated membrane (CCM) technologies.
Impurity Control
By selection of raw material, optimization of equipment and control of manufacturing process, the concentration of elements from impurity which cause the contamination of polymer electrolyte membrane is strictly controlled. The stability and lifetime of electrochemical equipment can be guaranteed.
Manufacturing Process
LNnewpower carbon paper products are manufactured through seven sub-process, using raw materials of high-modulus and high-strength carbon fiber as well as independent-developed functional resin.
During the manufacturing process, the intermediate products in each sub-process will be subject to quality control, the qualified products will proceed to the next process.
The intermediate and final products can adapt to different application scenarios, meet various customization requirement.
● The whole production line is based on roll-to-roll system
