I suspect this needs some moving parts to function - without a turbine's suction, you need some sort of a fan to pump air into the thing, and also a fuel pump. Most things with internal combustion require some kind of active cooling as well.
you need at least valves/regulators, but for self pressurized fuels like propane, butane, or even natural gas (CNG or LNG) you can probably get away with only that, and fans for air intake and cell cooling.
If using compressed natural gas you might not need a fuel pump at all.
