Asymtek DispenseJet® Systems Enable Consistent and Reliable Dispensing of Liquid Electrolyte Materials for Micro-fuel Cells and Electro-chemical Applications

Business Wire, April 21, 2009

CARLSBAD, Calif. -- Asymtek, a Nordson company (Nasdaq:NDSN) and leader in dispensing, conformal coating, and jetting technologies, announces a significant advancement in the dispensing of liquid electrolyte materials for the use in micro-fuel cells and other electro-chemical applications. Asymtek’s DispenseJet® systems overcome the dispensing challenges, such as material drying, clogging, and difficulty in creating patterns, that occur when trying to dispense these electrolyte materials in their liquid form.

Electrolyte materials (Nafion™ DuPont, Acidplex™ Asahi Chemical, and Flemion™ Asahi Glass) are used as part of the membrane electrode assembly (MEA) in a proton exchange membrane (PEM)-style fuel cell. Although these materials are typically applied in their solid sheet form, researchers can dispense the liquid form to create the specific design patterns needed and to improve fuel cell efficiency. Over time, liquid electrolyte materials change thickness and consistency, making them difficult to dispense with conventional dispensing or coating technologies. Asymtek’s DispenseJet (DJ) Series of jet dispensing technologies overcomes these challenges. Jet dispensing provides the precise control of a single droplet, controlling thousands of droplets that together form specific patterns without over-spray or clogging. Maintaining thickness or volume becomes easy with Asymtek’s Mass Flow Control (MFC) feature, which controls the amount of material required for dispensing without the guess work. The integrated balance scale uses Fluidmove® for Windows XP® software for automatic calibration and control of the DispenseJet® technology.

Asymtek’s jets are simple to use and operate, fast because z-axis motion is eliminated, accurate and highly repeatable, and provide a low cost of ownership. They are backed by over 15 years of Asymtek jetting experience.
