  "textContent": "An electrochemical engine in a vehicle comprises a fuel cell stack operable to produce electricity given hydrogen and oxygen, an air generator to supply oxygen to the fuel cell stack, and a first storage tank containing hydrogen-retention material which upon heating to a release temperature releases stored hydrogen to the fuel cell stack. The electrochemical engine further comprises a heat generator for producing heat for the hydrogen-retention material in the first storage tank. The electrochemical engine is located in a rear underbody compartment of the vehicle beneath a vehicle floor. The heat generator and the first storage tank are located longitudinally forward and closely adjacent to the fuel cell stack, and the air generator is longitudinally rearward and closely adjacent to the fuel cell stack.",
