One of the fastest growing markets for fuel cells is off-grid and back-up power applications, particularly in developing countries. Scientists are decreasing costs and minimising fuel issues to enhance market penetration.
Fuel cells convert the chemical bond energy in fuels such as bioethanol into electricity via a no-combustion electrochemical conversion process. Market potential for back-up and off-grid systems is supported by important advances in wireless communications systems. However, penetration has been slow, largely due to large initial investment costs and fuel logistics issues.
