Toyota Motor Corp's hydrogen fuel-cell concept car Toyota FCV PLUS is displayed at the 44th Tokyo Motor Show in Tokyo, Japan, October 28, 2015. Asia's two autos powerhouses, Japan and China, are jostling for supremacy in how future electric cars should generate their power â from batteries or hydrogen-powered fuel-cells. In a potentially high-stakes clash reminiscent of Sony versus Panasonic in the Beta-VHS video war in the 1980s, the winner could enjoy years of domination if their technology is adopted as a global standard by other manufacturers. This time, though, there should be a place in the autos market for both electric battery and hydrogen fuel-cell cars. The key question is which will power more mainstream cars.
