Hydrogen Fuel Cell: Electromechanical fuel cell that produces energy by combining hydrogen and oxygen atoms.

The variety of designs for MFCs has expanded rapidly within the last five years in the literature, however the patent protection has lagged behind.
This review will cover recent and important patents associated with MFC designs and progress.

In other embodiments of the invention, a cassette exchange system may comprise a container with a number of doors which may be opened by way of a user entering payment information through the payment system.
In one embodiment of the invention the door opens to allow usage of a cassette acceptor that contains a plurality of positions for accepting depleted cassettes and a cassette dispenser which has a plurality of positions for dispensing charged cassettes.
The plurality of positions may represent positions within a stack, slots, or other structurally defined positions.

  • Role of dissolved oxygen on the degradation mechanism of Reactive Green 19 and electricity generation in photocatalytic fuel cell .
  • This type of hydrogen storage material offers a convenient solution to store huge amounts of hydrogen at high density in a good form that avoids most of the prior art issues with cost and safety of storing and distributing hydrogen.
  • An oxidizer, such as oxygen, is supplied to the cathode, where the hydrogen ions from the anode absorb electrons from the latter and react with the oxygen to produce water.
  • As an additional option, the water may be processed for enhanced performance within an enhancement processing system 1510.
  • Generally, higher pressures and higher temperatures increase the permeability of hydrogen over the glass and therefore increase the rate of charging.
  • Reduced reactivity is the result of “coarsening” of platinum nanoparticles—a process whereby the nanoparticles increase in size and decrease in surface area.

This flexible micro hydrogen sensor is seen as a resistance to an electrochemical environment and low-temperature real-time measurement, also it can be placed in any position inside the proton battery.
A key part of fuel-cell energy-conversion processes is electro-oxidation of the fuel at the anode, but ways to improve electrocatalytic activity remain unclear.
Using ceria–metal structures, H2-oxidation reactions are shown to be dominated by electrocatalysis at the oxide/gas interface with minimal contributions from the oxide/metal/gas triple-phase boundaries.

The hydrogen storing material obtained from the cassette could be processed within the hydrogen recovery system to recovery hydrogen.
In a few embodiments, the hydrogen recovery system could have a conventional solid dividing device, such as a crusher, grinder, pulverizer, shreader, cutter, or other device, to form the solid hydrogen storage material into smaller portions.
Alternatively, a simpler hydrogen recovery system may be designed in case a powdered or otherwise finely divided solid, liquid or slurry is provided from the cassette.

The primary market is for residential applications, where pipeline gas will be the source of H2 used to power the house.
Other applications like the reforming of methanol for portable power applications such as for example laptop computers, cellular phones, and personnel digital equipment may also be discussed.

The state of the material can include factors as composition, hydrogen content, microstructure, temperature, pressure, and the like.
In some embodiments of the invention electrical or magnetic properties of the material may be used to evaluate the state of the material (e.g., its composition, microstructural features, temperature, etc.).

The dividing and inserting of the solid in to the hydrogen recovery system can also be done manually by an operator, as desired.
The hydrogen recovery system could also include a material addition system to controllably add material and reactants and a reaction chamber to controllably react the material with the reactants.
The recovered hydrogen could be stored in a buffer tank or other hydrogen storage container or provided to a hydrogen utilization system, such as a fuel cell, which may be contained within the hydrogen recovery system or may be external.
Byproducts or waste material may be removed from the reaction chamber to the right repository or processing.
Often, in order to achieve higher rates of diffusion and permeation, the present inventors contemplate heating the glass cassette housing to a temperature that is sufficient to supply a desired permeability to hydrogen.
