In the case of fuel cells, useful output energy is measured in electrical energy produced by the system. Input energy is the energy stored in the fuel. According to the U.S. Department of Energy, fuel cells are generally between 40 and 60% energy efficient. [65] This is higher than some other systems for energy generation.
Solid oxide fuel cells have a wide variety of applications, from use as auxiliary power units in vehicles to stationary power generation with outputs from 100 W to 2 MW. In 2009, Australian company, Ceramic Fuel Cells successfully achieved an efficiency of an SOFC device up to the previously theoretical mark of 60%.
A hydrogen fuel cell power plant is a type of fuel cell power plant (or station) which uses a hydrogen fuel cell to generate electricity for the power grid.They are larger in scale than backup generators such as the Bloom Energy Server and can be up to 60% efficient in converting hydrogen to electricity.
A commercially working cell in Japan called Eni-Farm is supported by the regional government, using natural gas to power up the fuel cell that then produces electricity and heated water. In 2013, 64% of global sales of the micro-combined heat and power fuel cell passed the conventional mechanical rotary systems in sales in 2012. [8]
Stationary fuel-cell applications (or stationary fuel-cell power systems) are applications for fuel cells that are either connected to the electric grid (distributed generation) to provide supplemental power and as emergency power system for critical areas, or installed as a grid-independent generator for on-site service.
The alkaline fuel cell (AFC), also known as the Bacon fuel cell after its British inventor, Francis Thomas Bacon, is one of the most developed fuel cell technologies. Alkaline fuel cells consume hydrogen and pure oxygen, to produce potable water, heat, and electricity. They are among the most efficient fuel cells, having the potential to reach 70%.
Initial production of fuel cell power units will be relatively small, with Honda executive Jay Joseph saying at an event on Wednesday that his company is aiming to deliver 2,000 fuel cell power ...
A protonic ceramic fuel cell or PCFC is a fuel cell based around a ceramic, solid, electrolyte material as the proton conductor from anode to cathode. [1] These fuel cells produce electricity by removing an electron from a hydrogen atom, pushing the charged hydrogen atom through the ceramic membrane, and returning the electron to the hydrogen ...
