What is a fuel cell?
Fuel cells convert chemical
energy directly into electrical energy, which makes fuel
cells particularly efficient. The essential technical
difference between fuel cells and batteries is that fuel
cells separate energy transformation and energy storage.
The fuel cell will continue to generate electrical
current as long as a gas of liquid medium is added. SFC
has patented a method of converting energy using fuel
cells that allows for miniaturization by focusing on
simplified fuel intake, sealing and electrical
configuration. We have also used low-cost materials and
mass production techniques to lower the cost of
manufacturing fuel cells. "Active Crossover Control" by
SFC permits active monitoring and minimization of the
negative methanol crossover effect, thus upping the fuel
cell’s performance. The result is an extremely short
startup time and highly efficient fuel cells by SFC.
We have developed our own
technology, which in turn, has provided the basis for
several patents. As a result, SFC enjoys a unique
technological and marketing edge in fuel-cell systems.
How do DMFC fuel cells work?
Low-temperature fuel cells are
suitable for mobile applications because they generate
electricity at low temperatures. The two main types are
hydrogen fuel cells and direct methanol fuel cells. SFC
has made a conscious decision to go with DMFC technology
because methanol is safer and more affordable.
Here is how a DMFC fuel cell works:
A mixture of methanol and water is
introduced to the anode side by a patented internal
water-management system. This enables us to employ 100%
pure methanol in our fuel cartridges. Ambient air is
pumped into the fuel cell on the cathode side. An
electrical circuit connects the anode and the cathode
sides. Upon contact with the platinum catalyst, methanol
releases its electrons which flow in the direction of
the cathode. At the same time, protons are released and
these penetrate the membrane to the cathode. There,
oxygen reacts with the proton and electrons to form pure
water.
During the chemical process, the fuel cell heats up to
about 40° C, releasing water as vapor and carbon
dioxide. The amount of water vapor and carbon dioxide
released is comparable to that found in the breath of a
child.
