In an air cleaner, a cassette is removably installed in an air cleaner housing. The cassette holds therein a filter formed by stacking a chemical filter and an air cleaner element. At the time of replacement or inspection of the filter, the cassette is pulled out of the air cleaner housing, and then the filter is removed from the cassette. Further, after completion of the replacement or inspection, the filter is placed in the cassette, and the cassette is installed in the air cleaner housing.

Method and apparatus for generating green electrical power. During a hydrogen gas storage mode, an electrolyzer generates a stream of hydrogen gas from water supplied by a water source and using power from an input power source. A hydrogen tank temporarily stores the stream of hydrogen. During a power generation mode, a fuel cell converts the stream of hydrogen gas from the tank into output electrical power by combining the hydrogen with oxygen. An inverter conditions and supplies the electrical power to a local load. A controller circuit uses a system parameter to adaptively switch between the storage mode and the power generation mode. In some cases, external power is supplied during the generation and storage of the hydrogen gas from an electrical grid or a local renewable source such as a set of solar panels. Respective grid-tied, solar-tied, grid-only, off-grid, and electric vehicle charging configurations are provided.

(EN) The present invention relates to the field of high efficiency and high flow hydrogen generation and purification from a hydrogen tank provided in the form of ammonia (NH3). In particular, the present invention describes in particular an innovative and compact system for the dissociation of ammonia and therefore the production of molecular hydrogen (H2), all in a cycle totally free of carbon (hence carbon emissions), as well as by the generation of nitrogen oxide and nitric dioxide (NOx).

Systems and methods for the production and use of both hydrogen and electricity. Embodiments of the disclosure include preparing processed hydrogen gas and regulated electricity from an energy source, and use of the gas and electricity in applications such as fuel cell electric vehicles and diesel supplementation.

The invention relates to a fuel cell system comprising: a fuel cell arrangement having at least one fuel cell and an air inlet, a feed line connected to the air inlet, a central air filter device which is connected to an inlet of the feed line either directly or via a distributor block, and a compressor which is located in the feed line and which is designed to suck in ambient air through the central air filter device and to convey said air through the feed line to the air inlet of the fuel cell arrangement. The invention also relates to a decentralized air filter system, which is designed to filter, downstream of the central filter device, air conveyed from the compressor to the air inlet. The decentralized air filter system comprises at least one decentralized air filter device which is located in the feed line between the compressor and the air inlet of the fuel cell arrangement, in the distributor block, or in the central air filter device.
