Fuel
Cell Technology For Cars
There are several types of fuel cells that have been
developed with emerging technologies in the alternative fuel
industry. Fuel cells convert energy like hydrogen into
electricity providing a cleaner burning fuel that emits no
pollution into the air. Fuel cell technologies have proven to
be life-changing for many people – and the world as well. With
the development of a part that can power a car with little to
no emissions will help the environment and reduce global
warming.
A polymer exchange membrane fuel cell was developed through
technologies that are endorsed by the Department of Energy. The
DOE is focusing on the PEMFC as the most likely candidate for
transportation applications. This type of fuel cell has a
higher power density and a relatively low operating temperature
(140 – 176 degrees Fahrenheit. The low operating temperature of
this fuel cell means that it doesn’t take very long for the
fuel cell to warm up and begin generating electricity.
Most of the fuel cell technologies being explored today are
based on using hydrogen as the main fuel source. With the
PEMFC, that is the case. It is the most prominent type of fuel
cell that is currently being looked at to be used in
alternative fuel vehicles.
There is also a direct methanol fuel cell that compares with
the PEMFC as far as its operating temperature. However, these
fuel cells aren’t as efficient. Another disadvantage to this
fuel cell is that it requires a large amount of platinum to act
as a catalyst. That alone makes it very expensive to run. We’re
sure, however, that emerging technologies in the fuel cell
market will improve on this and make it more cost efficient for
the average consumer.
One problem with fuel cells that technology has yet to solve
is that they are expensive to make. Many of the components of a
fuel cell are expensive thus making the whole fuel cell costly.
In order to be competitively priced (compared to
gasoline-powered vehicles), fuel cell systems must cost $35 per
kilowatt. Currently, the projected high-volume production price
is $110 per kilowatt.
Another problem with fuel cell technologies is that they
have yet to be converted enough to allow them to operate in
various weather conditions. The membranes must by hydrated in
order to transfer hydrogen protons. Therefore, researches must
find a way to develop fuel cell systems that can continue to
operate in sub-zero temperatures, low humidity environments and
high operating temperatures. At around 80 degrees Celsius,
hydration is lost without a high-pressure hydration system.
Fuel cell technologies are emerging and becoming more and
more in-depth every day. Before long, we’ll have a great
alternative to the gasoline powered car just with these tiny
fuel cells.
