Nanotechnology in Fuel Cells

There are several uses of nano materials; one of the considerable fields of nanotechnology is its uses in fuel cells. Fuel cells are promising alternatives to present power sources. In the large field of nanotechnology, polymer matrix based nano composites have become a prominent, one of the areas include polymer-based are fuel cells. Nano particles of platinum reduce the amount of platinum needed as electrode, or using nano particles of other materials to replace platinum entirely and thereby lower costs. Fuel cells contain membranes. Nanotechnology creates more efficient membranes. The effect of the large surfaces or interfaces of nano-sized carbon is important in nanotechnology treatment. The carbon nano fiber formation by polymer blend technology is progressing. We are now applying carbon nano fibers polymer composites as a candidate bipolar plate in fuel cells, utilizing the high modulus and high strength. A novel metallic porous medium with improved thermal and electrical conductivities and controllable porosity was developed based on micro/nano technology for its potential application in fuel cells. The small thickness and straight-pore feature of the novel material provides improved water management even at low flow rates. In this paper we try to introduce some aspects of nanotechnology used in fuel cells.
