A cathode supply fluid flow path is between an air source and a cathode fluid flow path inlet, and an inerting gas flow path is in operative fluid communication with a cathode fluid flow path outlet and a protected space. An anode supply fluid flow path is between a water source and an anode fluid flow path inlet, and an oxygen gas flow path is in operative fluid communication with an anode fluid flow path outlet and an aircraft occupant breathing device. An electrical connection is between a power source and the electrochemical cell.

Portable breathing equipment and related methods are disclosed. An example portable breathing equipment (PBE) includes a housing defining a cavity, a cover movably coupled to the housing, and a smoke hood provided in a wrapper and positioned in the cavity. A first portion of the wrapper couples to the housing and a second portion of the wrapper couples to the cover. At least one of the cover or the housing to cause the wrapper to tear to provide an access opening to allow access to the smoke hood when the cover moves from a closed position at which the cover seals the cavity of the housing and an open position at which the cover enables access to the cavity of the housing.

A gas demand device cycles through five successive operation phases: gas is prevented from flowing through the timing gas and demand gas flow paths; gas is allowed to flow through the timing gas flow path and gas is prevented from flowing through the demand gas flow path; gas is allowed to flow through the timing gas and demand gas flow paths; gas is prevented from flowing through the timing gas flow path and gas is allowed to flow through the demand gas flow path; and gas is prevented from flowing through the timing gas and demand gas flow paths.

A vehicle oxygen indication system that includes at least one oxygen source, and a plurality of oxygen assemblies. Each oxygen assembly includes a hose, a switch, a mask, and a flow indicator. The hose includes a lumen through which oxygen can flow from the oxygen source to the mask. The switch is switchable between a normal state when oxygen is not flowing from the oxygen source to the mask and a flow state where oxygen flows to the mask. When the switch is in the flow state, the flow indicator is switched from a static state to an indication state.
