Fuel cells offer improved efficiency, low emissions, and design flexibility for naval vessels, slashing shipbuilding costs. The Navy's ONR is testing a diesel fuel reformer to develop a proton exchange membrane (PEM) fuel cell, which will be capable of between 37-52 percent efficiency.
Researchers at NIST are studying how different factors affect fuel cell efficiency, including electrical and heating demands, temperatures, humidity, and power systems. The goal is to develop performance ratings that can help consumers understand the financial costs and benefits of fuel cells in various geographic and climate conditions.
Researchers have developed a new type of biofuel cell that runs off of alcohol and enzymes, potentially replacing rechargeable batteries. The cells can be charged instantly with a few milliliters of alcohol and may last up to a month without recharging.
A new study reports the results of several studies on determining the optimum materials for use as a proton exchange membrane in methanol-based fuel cells. The researchers believe that methanol-based fuel cells could be developed before hydrogen-based fuel cells, providing a convenient and accessible alternative for powering devices.
Researchers at ONR and DARPA are developing OSCAR, an oceanic fuel cell that harnesses organic matter in sea sediments to generate electricity. The early versions of OSCAR have been generating about 50 milliwatts per square meter, sufficient power for small calculators.
Case Western Reserve University has been awarded a $750,000 grant from the Ohio Eminent Scholars Program to support high-energy density fuel cell research. The university will also establish the Case Institute for Fuel Cells, where the appointed professor will lead technology development and education.
