Stanford University researchers create hybrid fuel cellJuly 9, 2011
Singular alternative fueling methods, such as solar or wind power, are well established.
Many of the technologies used for such methods have advanced to a point where further development is, more or less, counter-intuitive. Solar energy is already one of the more efficient forms of alternative fuel, and continuing to improve upon its faculties requires a level of technology not yet available. However, the world is still in need of more efficient alternative fuels. To meet demand, focus has shifted from singular fueling methods to hybrid systems, specifically solar hydrogen fuel cells.
A team of researchers at Stanford University in California have been developing hydrogen fuel cells that use solar energy as a catalyst. Conventional fuel cells use a platinum catalyst, which is both costly and inefficient, as well as its toll on the environment in the form of extensive excavation to obtain the material.
