The Federal Role in Fuel-cell Research and Development
ثبت نشده
چکیده
Fuel cells have the potential to provide environmentally-friendly sources of energy for transportation, portable, and stationary applications. Because fuel cells convert chemical energy directly to electrical energy, high efficiencies can be realized. Production of electrical power from fuel cells has several other advantages. There are no moving parts. Fuel cells operate noiselessly with no frictional wear. Because electrical energy is generated by an electrochemical process rather than by combustion, atmospheric pollutants produced are minimal.

Development and Simulation of a PEM Fuel Cell model for Prediction of Water Content and Power Generation
The proton exchange membrane (PEMFC) fuel cell represents the energy of the future, in parallel with hydrogen. However, this technology must meet many technical challenges related to performance and durability before being sold on a large scale. It is well known that these challenges are closely linked to water management. This paper develops and implements a model of PEM fuel for simulation to...
متن کاملInvestigation the performance of solid oxide fuel cells and the role of nanotechnology in its construction
Nanotechnology is well used in the development and performance improvement of solid oxide fuel cells (SOFCs). The high operating temperature of SOFCs (700-900 ° C) has led to serious shortcomings in their overall performance and durability. Hence, the high operating temperature has been reduced to the average temperature range of approximately 44-700 Celsius, which has improved performance and ...

متن کاملAdsorption of 1,1-Dimethylhydrazine by Hydrolysis Lignin
Many modern launch vehicles use unsymmetrical dimethylhydrazine (UDMH) as liquid fuel in the space program. UDMH is highly toxic and poses a serious threat to the environment and to humans. One of the most effective methods of UDMH neutralization in case of fuel spills is adsorption. This paper is the first to suggest using hydrolysis lignin as rocket fuel adsorbent. The research was based ...
