The drive to limit global warming depends on our ability to broadly limit the use of fossil fuels in many sectors including those related to electric power generation, industrial and residential uses and transportation. Rapidly increasing populations, and their striving for higher standards of living, continue to drive the rapid growth in vehicles for transportation and commerce. Fortunately, we are beginning to see rapid growth in electric vehicle (EV) sales that promise markedly reduced overall emissions of carbon dioxide into the atmosphere. By far, the lions share of EV sales are based on lithium battery powered vehicles. In this presentation, we examine the opportunities and challenges for hydrogen powered fuel cell vehicles that promise, at a minimum, extended operating range and rapid refueling. At the same time, one must confront the obvious present lack of adequate facilities for clean hydrogen generation, transportation and storage, raising the question of whether hydrogen powered vehicles will forever be the technology of the future? In light of these challenges, we report on progress that has been made on stationary reversible fuel cell/electrolysis cell devices capable of efficiently storing clean, but intermittent solar and wind energy, in the form of hydrogen, means for extending the life of such devices and the general challenges towards achieving cost effective and competitive fuel cell operated EVs.
