Global Status on Fuel Cells and Hydrogen Technology
Though, fuel cells and hydrogen technology is known to the scientific community for almost two centuries, in recent years, there has been a renewed interest due to global efforts to develop and use clean and efficient energy conversion technologies for sustainable development. Thus, this chapter presents an educative discussion on the current status of fuel cells and hydrogen technology. Brief discussion on the fuel cells operation principle, different types of fuel cells and historical developments is presented. Efforts by private companies for the development and deployment of fuel cells and current status of fuel cells for the different application sectors, namely; stationary power generation, transport sector and portable power sector have also been discussed. In general, within the last decade, there has been significant progress in the development and deployment of fuel cells in the three application sectors. However, stationary power generation sector has witnessed the most impressive increase in the use of fuel cells interms of both the system shipments (200% increase from 2010 to 2012) and megawatts shipped (250% increase from 2010 to 2012). On the availability of hydrogen, several technical challenges still remain concerning its production, storage and distribution. However, there is encouraging progress on the provision of hydrogen filling stations with about 208 available stations worldwide as of 2012, which will support the deployment of fuel cell vehicles. Thus, with the on-going serious academic research efforts, increasing investment by private companies and sustained governments’ support, the future for fuel cells and hydrogen technology looks bright.
