Optimizing Smart Grids

Increasing environmental issues, security of energy supply, drive research and development towards renewable energy sources (RES) worldwide. A key issue of RES, such as wind and solar resources, is intermittency. RES are not dispatchable, they exhibit large fluctuations, and are uncertain. The intermittency of RES can be absorbed by the hybrid combination of different RES [...]

Generating renewable electricity with Solar and Fuel Cell

Generating renewable electricity is an important way to reduce carbon dioxide (CO2) emissions and many countries are installing wind and solar power plants to help meet targets for cutting CO2. One drawback of these energy sources is their variability: the wind tends to blow intermittently and solar power is only available during the daytime. Hence [...]

WHAT is a fuel cell?

A Fuel Cell is an electrochemical device that continuously converts the chemical energy of the fuel (hydrogen) and an oxidant to DC electrical energy, heat and other reaction product (water). This reaction occurs inside the Membrane Electrode Assembly (MEA), an electrolyte membrane sandwiched between two gas diffusion electrodes.   Proton Exchange Membrane Fuel Cells (PEMFCs) [...]

End User Energy Cost with Portable Power Sources

Three major criteria should to be considered to choose a portable power source. The weight of the system, the cost of the energy produced and type of the fuel are the key drivers.

Uninterruptible Power Systems

Over 50% of failures for critical loads are due to the electrical supply and the hourly cost of downtime for the corresponding applications is generally very high. It is therefore vital for the modern economy, which is increasingly dependent on digital technologies, to solve the problems affecting the quality and the availability of the power [...]

GP300 HFC: EMC and water immersion tests

We are completing all the electrical and mechanical tests, aiming to certify our portable GP300 HFC system, in order to obtain the CE. In particular, in recent weeks we have carried out with our generator GP300 HFC electromagnetic compatibility (EMC) and water immersion tests (see photos below). EMC tests aim to detect any electromagnetic emission [...]

Effects of temporary reverse voltage on proton exchange membrane fuel cell performance

Polymer electrolyte membrane fuel cells are gaining great attention as a source of power generation for automotive applications. One key requirement for automotive applications is that the fuel cell must be tolerant of frequent start-stop cycling. A new decay mechanism related to local hydrogen starvation, which may be present during start-stop procedures, has been discovered. [...]
