Biomass Power Generation Using Liquid Tin Anode SOFC

Bentley J., Tao T., CellTech Power LLC, US

Currently biomass contributes only 1% of U.S. electric power despite available resources to provide over 20%. Barriers to increased use of biopower include low efficiency of current generators, high capital cost, low fuel energy, feedstock [...]

Exploiting Nanotubes in Fuel Cells

Boyang M., Imperial College London, UK

For many years, attempts to reduce the cost of polymer electrolyte membrane fuel cells have been halted by the large quantities of platinum required for their operation. This project explores the use of carbon nanotube [...]

Fuel Cells – Commercial Innovation Built on High Electrical Efficiency

Rowe T., Ceramic Fuel Cells Limited, AU

Ceramic Fuel Cells has developing an innovative solid oxide fuel cell technology that offers the world’s highest level of electrical conversion efficiency. CFCL’s fuel cells provide highly efficient and low-emission electricity from widely available natural [...]

New model of seven layers in PEMFC

Rakhshanpouri S., Rowshanzamir S., School of Chemical Engineering, IR

This model is an isothermal, isobar, one-dimensional and steady-state model for a polymer electrolyte fuel cell with a 117 Nafion membrane that considers seven-layer of fuel cell. In former years, Springer and colleagues presented the [...]

Performance Improvement of Fuel Cell using Platinum Functionalized Aligned Carbon Nanotubes

Liu D., Liu J., Goenaga G., Liu D., Liu J., Texas A&M University-Kingsville, US

Proton exchange membrane fuel cells (PEMFCs) are the energy conversion devices with ultrahigh efficiency, zero emission, and high flexibility of the fuel supplies. This study has optimized growth variables of the aligned carbon nanotubes (ACNT) [...]

Nanoengineering of a New Generation Proton Exchange Membrane for Micro Fuel Cells

Moghaddam S., Masel R., Shannon M., University of Illinois at Urbana-Champaign, US

We report development of the first viable silicon-based proton exchange membrane (PEM). This was achieved through self-assembly of 3-mercaptopropyl-trimethoxysilane (MPTMS) molecules inside extremely high aspect ratio torturous silicon nanopores. This development can greatly benefit the [...]

A Novel Anode Electrode for Direct Borohydride Fuel Cell

Kim K-J, Bernas R., Miley G.H., Luo N., Yang X., University of Illinois, US

As part of the development of a portable fuel cell using direct sodium Borohydride fuel, deposition methods of the catalysis on the diffusion layer have been studied. In earlier studies catalyst deposition onto a porous [...]

Energy-efficient electrochemical CO2 capture from the atmosphere

Eisaman M.D., Schwartz D.E., Amic S., Larner D., Zesch J., Littau K., Palo Alto Research Center, US

In this contribution, we report on the experimental demonstration of a continuously operating modified fuel cell capable of capturing CO2 at atmospheric concentrations with record efficiency. The atmosphere provides O2 and CO2 at the cathode, [...]
