TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Generator: (G1) further comprises device (d1) coupled (preferably detachably) to an inlet port of (r1) for adding the aqueous solution all at once into (r1); an outlet port of (r1); a support for supporting the catalyst on a surface of the support; a controller in communication with a actuator via electronic or pneumatic device; and a fluid separation device for removing liquid from generated hydrogen gas, where the hydrogen gas flows through the fluid separation device to the outlet port. (r2) further comprises an outlet port containing a first fluid control device for controlling flow through the outlet port. The inlet port of (r2) comprises a second fluid control device for controlling fluid through the inlet port. The inlet port comprises a first fluid control device for controlling flow through the inlet port. The outlet port comprises a second fluid control device for controlling flow through the outlet port. The first/second fluid control device is check valve, ball valve, gate valve, globe valve and/or needle valve. The first/second fluid control device further comprises at least one actuator. (c1)/(c2) is supported on a porous substrate (preferably foam, especially metal). A surface of the substrate is treated to increase a hydrophilic nature of the surface. The pores of the porous substrate contain (c1). At least a portion of the catalyst is applied to a surface of the porous substrate. (c2) further comprises a catalyst (5 - 20, preferably 6 - 12 wt.%). (G2) further comprises a support for supporting the catalyst on a surface of the support; a controller in communication with a actuator via electronic or pneumatic device; and a fluid separation device for removing liquid from generated hydrogen gas, where the hydrogen gas flows through the fluid separation device to the outlet port. The surface of the porous material is coated with a catalyst. (c2) is supported on a foam substrate (s1). The device for adjusting a flow rate of an aqueous solution into (r2) comprises a plunger slideably disposed within the reservoir for pressurizing the aqueous solution; a gas source in fluid communication with a gas side of the plunger or with an interior of the water chamber; a controller for adjusting an electrical current flowing from a power source to the electrolyzer; a hydrogen fed electrochemical pump for pumping the aqueous solution from the reservoir to (r2); and a gas source for pressurizing the aqueous solution reservoir. The gas source is an electrolyzer for controllably generating the gas for delivery to the gas side of the plunger or to the interior of the water chamber. A gas outlet of the electrolyzer is in fluid communication with the gas side of the plunger. The controller adjusts the electrical current in response to a hydrogen generation demand. (G2) further comprises a water chamber for containing the aqueous solution reservoir. The water reservoir is an inflatable bladder. At least one gas outlet of the electrolyzer is in fluid communication with the interior of the water chamber. The water inlet of the electrolyzer is in fluid communication with an interior of the reservoir or the water chamber. The water chamber is adapted for storing water outside the reservoir. The electrolyzer controllably generates and delivers hydrogen gas and/or oxygen gas to the water chamber. The delivered gas from the electrolyzer is for applying pressure to the inflatable bladder in proportion to a volume of the delivered gas.
