  Low-Cost FDM-Printed Microfluidic Droplet Generators with Vertical Flow-Focusing Channels

  By D. M. C. T. Dissanayake, L. C. Menikarachchi, K. B. Wijayaratne, B. S. Nanayakkara, L. K. Narangammana

  Abstract: *Author for CorrespondenceL. K. NarangammanaE-mail: [email protected] Low-cost fabrication methods are now essential for expanding access to microfluidic technologies in biological and laboratory applications. In this work, we present a fused deposition modeling (FDM) based approach for the rapid fabrication of monolithic microfluidic droplet generators incorporating several T-junction and specific flow-focusing geometries, including a novel vertical channel configuration. All devices were fabricated without post-processing or bonding, demonstrating a simple and cost-effective …

  Review On Bipolar Plate Geometric Design and Materials for Proton Exchange Membrane Fuel Cell Applications

  By Parthiban Siva Gurunathan, Karthikeyan Subramanian, Venkatesh Kumar Velmurugan

  Abstract: Abstract Bipolar plates (BPs) are vital components in proton exchange membrane fuel cells (PEMFCs), performing multiple essential functions that directly influence system efficiency, durability, and overall operational performance. They ensure uniform distribution of reactant gases across the active area, provide electrical conductivity between adjacent cells, assist in effective thermal management by dissipating heat generated during electrochemical reactions, and maintain proper sealing to prevent leakage of gases and coolant. Among these …
