Abstract: An electrical battery for multi-cellular interconnection in series, parallel or series and parallel has a protrusion and a recess, such as a tongue and a groove, extending on outer surfaces of the sidewalls of the battery case such that when a protrusion of one battery is slid into a recess of another, the two batteries are electrically connected by the portions of the protrusion and the recess that are made of electrically conductive materials connected to the voltage producing elements inside the case. The battery further includes hollow plug-in posts and plug-in pins at the top and the bottom of the case that are connected to the voltage producing elements of the battery so that when the plug-in pins of one battery are inserted into the plug-in posts of another, the two batteries are in electrical interconnection. The battery also includes an electrolyte recirculation, gas purging, and automatic watering systems.

Abstract: Fuel cell electrodes are described which comprise a non-woven network of conductive fibers, such as a carbon fleece, nickel foam sheet or stainless steel wool layer, plus additional activated carbon material, carrying one or more catalyst components and at least one polymeric substance as binder and/or repellancy agent to establish three zone interfaces (liquid-solid-liquid) or three phase interfaces (gas-liquid-solid). The electroactive catalyzed material is embedded into the conductive structure by specified deposition processes, such as coating, blading or spraying.

Abstract: This method for hydrogen production from ammonia is based on the catalytic dissociation of gaseous ammonia in a cracker. A catalytic fixed bed is used. The ammonia cracker supplies a fuel cell (for example, an alkaline fuel cell AFC) with a mixture of hydrogen and nitrogen. Most of the supplied hydrogen is burned in the ammonia cracker for the supply of the energy needed for the ammonia dissociation process.
