New Conductive Polymer Coating to Dramatically Reduce Fuel Cell Cost

Janina Lazo-Cruz — Thu, 25 Oct 2012 05:00:32 +0000

HyperSolar Inc. has recently filed for a joint patent with University of California – Santa Barbara for a recent discovery on a polymer coating that acts as both protective and electrically conductive layer, which may find a broad field of applications, especially fuel cells. Unlike metals and semiconductors, polymers are intrinsically electrically non-conducting. That’s why […]

A new magnesium fuel cell using saltwater as electrolyte is now being commercialized by Tokyo-based Furukawa Battery, a company specialized in power systems. The electrolyte, just like in any other fuel cell, carries charged particles from one electrode to another, and electricity is generated following this reaction. “It is now possible to install an inexpensive […]

MIT researchers, along with their colleagues from the Brookhaven National Laboratory and the Japan Institute of Science and Technology have found a method of decreasing the amount of platinum used in DMFCs by increasing the efficiency of the fuel cell's electrodes. Others have tried to replace the platinum on the cathode with a liquid regenerating catalyst system (catholyte solution).

New Palladium Nanoparticles Making Fuel Cells Better

Ovidiu Sandru — Mon, 23 Mar 2009 12:30:10 +0000

Nowadays, the cost of a hydrogen fuel cell is mostly increased by the cost of its components, and mostly by platinum. In the search for finding better materials for making fuel cells, researchers have already found alternatives to the expensive platinum a long time ago, but they were not as efficient. One of this substitute materials is palladium - far cheaper and much more abundant, but that didn't have enough surface area to make the fuel cell catalysis efficient.
