Step on the gas -- New fuel cell design adds control, reduces complexity

When Princeton University engineers want to increase the power output of their new fuel cell, they just give it a little more gas – hydrogen gas, to be exact. This simple control mechanism, which varies the flow of hydrogen fuel to control the power generated, was previously thought impossible and is a potentially major development in fuel cell technology.
