DESCRIPTION:Energy demand has largely increased over the last century. The
  current major energy source has been fossil fuel in the form of coal\, pe
 troleum and gas. Pollution\, carbon emission\, becoming scarce and expensi
 ve are the main reasons why we don’t want to relay on fossil fuel anymor
 e. However the transition to non-fossil fuel energy usage will be gradual 
 and there are many benefits in storing energy in chemical form as a fuel. 
 Due to its versatile use and efficiency at operation fuel is mostly conver
 ted into electricity. Conversion efficiency of the chemical energy to elec
 tricity is one of the major points effecting energy loss and overall effic
 iency of our energy consumption. Here I will focus on the conversion proce
 ss from chemical energy to electricity specifically by electrochemical dev
 ices such as fuel cells. Traditionally\, fuel combustion generates heat an
 d mechanical force with limited efficiency which is then converted into el
 ectricity by very efficient electromagnetic devices such as dynamos and al
 ternators\, resulting in overall a low efficiency electricity generation. 
 Fuel cells and in particular Solid Oxide Fuel Cells (SOFCs) offer the pote
 ntial for the environmentally friendly and efficient source of electricity
  generation from variety of fuels. Their key feature is the direct convers
 ion of the chemical energy into electricity without the fundamental effici
 ency limit of the heat engines of ~60 % (the Carnot cycle). With this talk
  I hope to create a nice discussion platform for the energy plan for the f
 uture of our planet.
