Field of use: electrochemistry and energy courses, fuel cells and FC systems engineering, electromechanics, renewable energy.

Applications: classroom instruction, hands-on learning, advanced classes, vocational/professional training, R&D projects.

The “power tool” pack integrates all the components required to operate the electric pruning shear autonomously from the fuel cell without any other power source but hydrogen.
The power generator relies on a fuel cell/super capacitors hybrid architecture to supply all the power needed by the cutter while insuring autonomy and high cutting frequency.

The pruning shear, requiring 670W of power on a strong cut, takes advantage of the hybrid architecture to operate from a fuel cell of only 50W. The pruning shear, usually powered by conventional belt-carried batteries, is a common tool in vineyards and professional gardening.


The whole pack is designed to fit education projects on fuel cells. The pruning shear and power electronics module are protected with suitable clear casing to prevent any hazardous operation. All the components are equipped with sensors (current, voltage, temperature) and are connected to a signal converter module for PC data logging. The LabviewTM and MatlabTM based software allows a complete modeling of the system to understand the energy transfer, efficiencies, power and energy parameters. It is also possible to simulate other applications than the pruning shear.
The Power Tool Pack is delivered ready-to-use.

Experiments
The Power Tool package is particularly suitable for teachers and instructors wishing to rely on a didactic system that is very close to a commercial/practical fuel cell application.

Beyond the hydrogen energy education, the Power Tool pack leads to a pragmatic comparison between two energy storage techniques: conventional rechargeable batteries and fuel cells (weight, operation range, durability, form factor, embedding factor, usage mode,…).The included software delivers real-time operating parameters and leads the user through an analytical work to compare the theoretical model to the practical case.

The numerical model and physical fuel cell can be used with other applications than the pruner, for example in a student project (RC vehicle integration, electric bike range extender, PV coupling, battery charger…).The training course material supplied with the Power Tool Pack brings a multi-technologies approach in the fields of energy management, use and transformation of matter, data transfer and information processing. Functional analysis and modeling are put at the forefront of product design with numerous supports.

Included software tools and libraries allow efficient power tool performance analysis depending on the operating mode like diameter of wood cut, cut frequency, full or half cycle cut. Investigation can be achieved by simulating the system with varying parameters and configurations and then confirmation by experimentation. Numerous data are fed back by the system to the user: power, currents, voltages, energy produced and consumed at several system stages, gas consumption, cell temperature…).

CAD files and electronics diagrams supplied, as well as a voluntarily open architecture (open source code) offer a fantastic working environment for educational projects, valorizing design and innovation methodologies. Students will be able to produce virtual and real fuel cell powered prototypes.
