FlickrSandia researchers have developed new high-resolution magic angle spinning (HRMAS) nuclear magnetic resonance (NMR) spectroscopy techniques to investigate diffusion in polymer membranes. By coupling HRMAS NMR with pulsed field gradient (PFG) diffusion techniques, the team has demonstrated the unprecedented resolution of individual chemical species within a series of fuel cell anion exchange membranes (AEMs). The [...]
Sandia National Laboratories’ unique experimental capabilities to quantify the effects of hydrogen on structural materials at high pressures are one of the reasons it was chosen to be a part of the International Institute for Carbon-Neutral Energy Research (I2CNER). I2CNER is an international consortium established in Japan in 2007 with a main objective to develop [...]
At Sandia National Laboratories, researcher Cy Fujimoto, in partnership with Automotive Fuel Cell Cooperation (AFCC), is developing a polymer electrolyte membrane (PEM) that can operate optimally with minimum on-board humidification and low gas crossover. Current fuel cell vehicles run optimally when the air and hydrogen fuel is humidified, which requires high pressures and additional systems [...]
Sandia National Laboratories has been working with General Motors (GM) for over 30 years. In the last few years, this partnership has become a strategic alliance, which includes a cooperative research and development agreement (CRADA), making it easier for the partners to work together. Our parthership’s research focus areas include systems modeling for energy, infrastructure, [...]
On October 24, 2012, the National Academy of Sciences (NAS) released the prepublication version of the report, “Sustainable Development of Algal Biofuels.” Although algal biofuels are gaining attention as a domestic renewable fuel source, the study found that with current technologies, scaling up production to meet even 5% of U.S. transportation fuel needs could create [...]
