Membrane electrode assemblies (MEAs) for high temperature polymer electrolyte membrane (PEM) fuel cells are currently being developed by Advent Technologies for the following applications
Stationary applications
Applications of fuel cells for stationary power have several attributes that make them an attractive alternative to incumbent technologies. These attributes include high reliability and the ability to serve remote off-grid locations. Additionally, the opportunity for co-generation creates even greater energy efficiency. Stationary fuel cells can be used in back-up applications where an uninterruptible power supply is critical, such as hospitals, computer data/banking centers and telecommunication transmitter towers.
As a replacement to conventional combustion power plants, generators or batteries, fuel cells will be able to generate electricity more efficiently than many of today`s technologies, and with less environmental impact (noise and emissions). The fuel cell technologies being developed for this power plant will generate electricity from hydrogen (supplied directly or via hydrogen-rich fuels like NG, propane, etc.)
Transportation applications
Transportation fuel cells have several advantages compared to internal combustion engines (ICEs) or diesels.
They are far more energy efficient, they do not rely on oil and they produce fewer emissions (as low as zero, depending upon the fuel used).
For these reasons, governments are particularly interested in promoting the use of fuel cells in the transport sector.
Portable applications
Fuel cells are an excellent source of power for emergency and recreational uses where access to the electric grid is restricted or simply unavailable. Portable devices offer great potential as back-up power supplies. Fuel cell power sources are also being developed for portable electronic devices.
In these applications, the fuel cell would provide a much longer life than a battery (perhaps ten times longer), and "refuel" quickly with a liquid or gaseous fuel. Another advantage of fuel cells over batteries is that they provide a much higher power density. Finally, technology in this area has also focused on direct methanol/ethanol fuel cells (DMFC/DEFC). |
