Fuell cells can be divided by the fuel consumed. The two currently most common are methanol and hydrogen. The by- products of both are environmentally friendly.
   Methanol production can be energy intensive and it has transporting problems.
   Hydrogen production on a large scale requires much energy and it can have transporting problems when under pressure.
   Recently, technical advances are providing economic renewable hydrogen cartridges for smaller scale applications .
     We are now offering educational kits and toys to introduce this new method. Soon there will be more commercial applications
