MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202641017387 A) filed by Anna University, Chennai, Tamil Nadu, on Feb. 17, for 'herringbone-arrowhead flow field channel bipolar plate for fuel cells.'
Inventor(s) include R. Mohammed Abdul Kadar; K. Shanmuga Sundaram; M. Pradeep Kumar; and S. Jeno.
The application for the patent was published on May 29, under issue no. 22/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a metallic bipolar plate (1) for proton exchange membrane fuel cells (PEMFCs) incorporating a herringbone-arrowhead flow field channel (2) configuration. The bipolar plate comprises a plurality of angled and intersecting flow channels arranged in an arrowhead-shaped herringbone pattern to enhance reactant gas distribution across the membrane electrode assembly. The channel geometry induces passive swirling and transverse flow components, thereby improving reactant mixing, reducing concentration gradients, and facilitating effective removal of liquid water generated during electrochemical reactions. The design minimizes flooding, maintains optimal membrane hydration, and reduces pressure drop across the flow field. The bipolar plate (1) is preferably manufactured as a single-piece metallic component, providing high mechanical strength, corrosion resistance, and reduced weight. The invention enhances fuel cell efficiency, durability, and operational stability, and is suitable for automotive, stationary, and portable PEM fuel cell applications."
