This application relates to a fuel dispensing system and method for safely regulating transfer of fuel between a fuel dispenser and a fuel recipient. The fuel dispensing system may be used, for example, to replenish electric vehicles that use refillable electrochemical power generation systems, such as fuel cell hybrid systems using hydrogen fuel. The system employs a combination of interlocks and other safety features specifically adapted for high-risk indoor environments. Fueling cannot commence until the dispenser and the recipient are electrically bonded to minimize the risk of spark generation. The system may include, for example, a fuel supply subsystem for preventing fuel flow except during a fueling session, an immobilization subsystem for preventing relative movement of the dispenser and the recipient during a fueling session, a communication subsystem for enabling data exchange between the dispenser and the recipient, and a leak detection subsystem for monitoring the fueling site for fuel leaks. In order to minimize or negate the risk that hazardous and/or flammable products could be exposed to the atmosphere during a fueling session, the system ensures that fueling cannot commence until multiple safety criteria are satisfied.
