A hydrogen fuel supply system includes a hydrogen generator for generating hydrogen from an energy source at an outlet pressure. An outlet conduit feeds the hydrogen to a user. A controller controls the hydrogen generator to produce hydrogen at the outlet pressure. An input interface receives user demand data and activates the controller in accordance with the user demand data.

Energy distribution network

A hydrogen energy system for a facility that is disposed off-board a vehicle. The system includes a hydrogen generator disposed at the facility for generating hydrogen by water electrolysis, a hydrogen storage apparatus for storing at least some of the hydrogen generated by the hydrogen generator, and a controller having a computer processor for receiving and processing certain control inputs. The controller is operatively connected to the hydrogen generator for controlling the generation of hydrogen based on the control inputs.

A hydrogen energy system is provided for one or more buildings. The system includes a hydrogen generator; at least one zone controller for receiving and processing demands from at least one hydrogen user associated with at least one zone of the one or more buildings; and a unit controller for receiving and processing hydrogen demand data received from the at least one zone controller.

An energy distribution network is provided including an energy source; a hydrogen production facility connected to the energy source; a recipient for hydrogen from the hydrogen production facility; and a controller. The controller controls the production of hydrogen by the hydrogen production facility based on inputs including energy resource availability.

The present invention relates to electrochemical cells and electrochemical systems using a one piece or unitary electrode plate hereinafter also referred to as a double electrode plate (DEP) which serves to electrically connect two adjacent cell compartments and wherein the current flow in the electrodes is parallel to the working face of the electrode. In the cell designs disclosed herein the cells are assembled as a contiguous stack of cells (cell stack) appearing similar to a filter press where the electrical connections between adjacent cells are made using the double electrode plate. In one aspect of the invention there is provided a single stack electrolyser (SSE) utilizing a folded double electrode plate to connect adjacent cells in a single stack. An insulating wall separates compartments of adjacent electrode pair assemblies connected by the double electrode plate in the SSE.

Electrochemical cell using a folded double electrode plate

The present invention relates to electrochemical cells and electrochemical systems using a one piece or unitary electrode plate hereinafter also referred to as a double electrode plate (DEP) which serves to electrically connect two adjacent cell compartments and wherein the current flow in the electrodes is parallel to the working face of the electrode. In the cell designs disclosed, the cells are assembled as a contiguous stack of cells (cell stack) appearing similar to a filter press where the electrical connections between adjacent cells are made using the double electrode plate.

Electrochemical cell utilizing rigid support members

An improved electrochemical system includes at least two cells. Each cell defines an anolyte chamber and a catholyte chamber, and includes at least an anode electrode adjacent to the anolyte chamber, and a cathode electrode adjacent to the catholyte chamber. At least one unitary one piece double electrode plate is provided having an electrically conducting frame. At least two single electrode plates are provided, each including an electrically conducting frame for supporting an anode electrode or a cathode electrode. A separator is between the catholyte and anolyte chambers and has at least a peripheral frame formed of a compressible elastomer. An anolyte chamber forming frame formed of a compressible elastomer and a catholyte chamber forming frame member formed of a compressible elastomer are provided within each cell. The anolyte and catholyte chamber forming frame members and the peripheral frame of the separator are compressed to form fluid tight seals when the electrochemical system is assembled. The anolyte and catholye chamber forming frame members extend beyond edges of the electronically conducting frames to allow of the peripheral frame being bonded in direct abutment with the anolyte and catholyte chamber forming frame members.
