Determination of the coefficients of friction
Our laboratory has just installed a system for measuring the coefficient of friction to meet the international standard ISO 8295.

Given the difficulties to miniaturiaze these systems, the first commercially available fuel cells are the most bulky. They cover the fields of electricity production, domectic cogeneration and transport (electric cars and buses).

The hydrogen fuel cell is the most promising technology because it produce only water. However the synthesis, storage and supply of dihydrogen H2 are a major part of the challenge ahead. Indedd dihydrogen exists in large amount only combined with oxygen (i.e. water H2O), sulfur (H2S) and carbon (fossil fuels).
Currently dihydrogen can be stored and supplied under the form of;
- gas : compressed in tanks (from 350 to 700 bar) ;
- solid : combined with metallic hydrides ;
- liquid : liquified or chemically combined (methanol or methane).
The efficiency of hydrogen fuel cell can reach 50-60% versus 25% for a power generator. Nevertheless taking into consideration the synthesis of dihydrogen and its liquefaction/compression, this efficiency drops drastically. Furthermore one of the main risks identified for all storage technologies is a hydrogen leak, with consequences that will vary depending on the storage pressure. In a confined & poorly ventilated area, a hazardous atmosphere could be generated.
HySiLabs, a young startup created in Aix-Marseille University and located in the technology park of environment of Arbois, provides the only source of liquid hydrogen in the grid-off energy market (not connected to the electricity grid). By mastering this innovation energy vector, the HySiLabs solution allows to enjoy the energetic benefits of the hydrogen vector without the problem related to the storage.
Now HySiLabs researches optimum conditions for for the production of hydrogen according to the vectors and flows required for the working of different kinds of hydrogen fuel cells. To be supported in the conception of hydrogen generators prototypes, HySiLabs has approached Matériau Ingénierie and the Pple TESLA EIG. To carried out the acquisition of data for process optimization, Matériau Ingénierie has selected and implemented the suitable sensors.
Eventually HySiLabs may use the prototype as a demonstrator in the conferences about grid-off energy when all the testing phases will be realized.
