Developed

  1. The Sandia team originally developed the CR5 to generate hydrogen for use in fuel cells. (Web site)

Explosion

  1. The explosion happened in the fuel cells of the spacecraft's service module approximately 56 hours after lift-off. (Web site)
  2. An explosion had damaged the electrical system and two of the three fuel cells, which meant a moon landing was out of the question.

Buses

  1. Fuel cells capable of powering automobiles and buses have been and are being developed.

Operation

  1. Fuel cells require hydrogen for operation.
  2. Solid oxide fuel cells (SOFCs) may be potential source for cogeneration, due to the high temperature heat generated by their operation.

Natural

  1. Most fuel cells use natural gas (composed mainly of methane) as the source of hydrogen.

Development

  1. DaimlerChrysler is a pioneer and leading player in the development of fuel cells for the automobile. (Web site)
  2. Fuel Cells - Natural gas fuel cell technologies are in development for the generation of electricity. (Web site)
  3. There are several types of fuel cells currently under development, each with its own advantages, limitations, and potential applications.

Weight

  1. However, at the moment the high cost and weight of batteries and the lack of affordable onboard electric generators such as fuel cells restrict their use.

Diesel

  1. And development work is beginning for such entirely new power technologies as fuel cells that can eventually replace the diesel engine altogether.

Promising

  1. Fuel cells that use modified formic acid are promising.

Cost

  1. Called the free-piston engine, it could be used to generate electricity as efficiently as fuel cells yet cost less.

Surface

  1. Submarines use batteries (charged by diesel or gasoline engines at the surface), nuclear power, or fuel cells [ 11] run electric motor driven propellers. (Web site)

Combustion

  1. Because there is no combustion, fuel cells give off few emissions; because there are no moving parts, fuel cells are quiet. (Web site)
