Dynamics of proton exchange membrane fuel cells (PEMFC) with hydrogen storage system for generating part of Hercules airplanes electrical energy is presented. Feasibility of using fuel cell (FC) for this airplane is evaluated by means of simulations. Temperature change and dual layer capacity effect are considered in all simulations. Using a three-level 3-phase inverter, FC's output voltage is ...

The paper describes an EasyTest cell developed for simple, safe and inexpensive to run testing and optimisation of the active materials (catalysts, catalytic supports, polymer membrane electrolytes) and electrode structures utilized in PEM Fuel cells and Electrolysers. The main advantages of the new EasyTest technique are demonstrated by a comparative study on the performance of two types of me...

• Ion and water permeation is modeled for PEM electrolysers using tap water. transport depends on hardness ion mobility in Water only occurs powered operation due to migration. Auxiliary cathode anolytic compartment reduces by approx. 18% While electrolysis could be a favourable technique situ sanitization with ozone, its application mainly limited the use of ultrapure achieve sufficient long-t...

The main condition that all countries have agreed on about the future of the earth activities is to keep it clean and free of pollution. For using energy and still keeping the earth clean, the final solution is to use alternative fuels. Hydrogen, as an alternative fuel, would be a good choice in this respect. Hydrogen could be produced by photoelectrolysis of water via a microbial cell, which i...

This paper communicates on an innovative, laboratory size alkaline water electrolyser (AWE) system, capable of efficiently producing ultra-pure hydrogen and oxygen gases. The system is composed a zero-gap, bipolar-electrode stack, equipped with polymer-based membrane, along two drying columns for effective purification H2 O2 gaseous products. An optimal electrochemical efficiency the stack prov...

While hydrogen generation by alkaline water electrolysis is a well-established, mature technology and currently the lowest capital cost electrolyser option; polymer electrolyte membrane electrolysers (PEMWEs) have made major advances in terms of cost, efficiency, durability, installed capacity growing rapidly. This makes promising candidate for large-scale production, especially energy storage ...
