High Speed Air Compressor for a Fuel Cell System for Use in a Vehicle

Dear Colleagues,

In order to lower the human contribution to climate change, the reduction of CO₂ emissions is a global concern. New drive concepts such as battery electric cars have a high potential to lower the carbon foot print of personal mobility. Other approaches such as fuel cell cars are usually neglected due to their comparatively poor efficiency. However, they have great advantages in terms of ranges and refueling time. An important component of fuel cell drives with high potential for savings and optimization is the electric air compressor.

This research project is, therefore, concerned with the design and further development of an electrically driven air compressor, aiming at a technology readiness level of 8. In addition to increasing the efficiency by optimizing spiral groove bearings, air flow and temperature management, the goal is also to reduce costs. Therefore, material selection and simplification of production and assembly are of particular concern.

This Special Issue covers the following main topics in particular:

• Shaft bearing and materials;
• Aerodynamics and map extending and stabilizing measures;
• Power electronics for controlling the air compressor control;
• Overall engine design and construction of test vehicles;
• Component testing;
• Manufacturing concept.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Machines is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
