A regenerative fuel cell system is provided having at least one hydrogen storage container fluidly coupled to at least one hydrogen generator and at least one power generator. Each power generator further includes a fuel cell fluidly coupled to the hydrogen storage container, an electric energy storage device, and an unregulated dc bus electrically connected to said fuel cell and said electric storage device. The system further provides for a health monitoring system for determining the occurrence of critical events which may necessitate the disabling of the system.

Hydrogen storage system and method of operation thereof

A fuel cell system includes a fuel cell apparatus and a heat storage device. The heat storage device is in fluid communication with and responsive to the fuel cell apparatus and is adapted to receive and store heat from and deliver heat to the fuel cell apparatus.

Fuel cell system with thermal management and method of operation thereof

A modular power system having separately removable electrolysis and power modules, each with separate sets of connection ports, is disclosed. The connection port set of the electrolysis module is adapted for operable communication with a water supply, a hydrogen storage device, and the power module, and the connection port set of the power module is adapted for operable communication with the water supply, the hydrogen storage device, and the electrolysis module.

Method and apparatus for providing modular power

A method of monitoring the operation of a gas sensor is disclosed. A system signal is provided in response to sensing first or second system conditions, and a gas concentration signal is provided in response to sensing first or second gas concentration levels of a gas. In response to the system and gas concentration signals, a signal indicating the operating condition of the gas sensor is provided.

Method of monitoring the operation of gas sensor and system therefor

An electrochemical cell system comprises: a fuel cell module comprising a fuel cell outlet, an electrolysis module comprising an electrolysis water inlet in fluid communication with a water storage device and a hydrogen gas outlet in fluid communication with a hydrogen storage device, and a drainage system disposed downstream of the fuel cell hydrogen outlet and upstream of the water storage device and configured to remove water from the electrochemical cell system upon water within the water storage device attaining a selected level.
