Presented are battery assemblies with integrated fuel tanks, methods for making/using such battery assemblies, and fuel cell electric vehicles having rechargeable traction battery packs with integrated fiber-composite hydrogen fuel tanks. A rechargeable energy storage system (RESS) assembly includes a battery pack housing with an internal battery module compartment located between two tank mounting cavities. Each mounting cavity is recessed into a respective lateral side of the battery pack housing. Multiple rechargeable battery modules are electrically interconnected with one another and mounted inside the battery module compartment. Each battery module contains multiple battery cells, such as a stack of series-connected lithium-ion pouch cells. A fuel tank is mounted in each of the tank mounting cavities on the lateral sides of the battery pack housing. Each fuel tank, which may be fabricated from a carbon fiber reinforced polymer, stores and selectively dispenses a fuel, such as a hydrogen-rich, compressed gas fuel.
