One giant leap towards more sustainable cars.Yesterday, General Motors and Honda announced an $85 million joint venture to manufacturing fuel cells for cars starting in 2020. The two automakers started collaborating on fuel cell development in 2013, but the new JV will up the ante by turning their combined research into a bigger reality. Compared to batteries, fuel cells offer longer range and are quick to refuel, so more fuel cells means more options for zero-emissions cars coming our way.
