A method for manufacturing a plastic part forming a human-machine control interface includes formation of a decorative film, formation of a technical film including a layer of haptic actuators and a layer of capacitive sensors, assembly to form an interface film, positioning in an injection mould, including an upper portion and a lower portion including a moveable support pad capable of coming into contact with the interface film such that a thickness is left free between the interface film and the lower portion of the injection mould outside of the support pad, injection of a plastic material into the free thickness on either side of the support pad, and opening of the injection mould and ejection of the plastic part formed.

A voltage transformer including a beam or membrane made of a first polymer material having a resonance frequency in the range from 1 Hz to 1,000 Hz and including on the beam or membrane a stack successively including: a first electrode; a first piezoelectric layer made of a second polymer material; a second electrode; a second piezoelectric layer made of a third polymer material identical to the second polymer material or different from the second polymer material; and a third electrode.

Described herein are articles, systems, and methods relating to fuel cell systems that include anode chambers with variable volumes. The volume of the anode chamber may be relatively small or essentially zero upon start up to prevent influx of contaminants that would have to be purged from the system. As fuel is directed into the anode chamber, the chamber volume increases to accommodate the flow of fuel.

Anode chambers with variable volumes

The fuel cell includes an anode chamber having a hydrogen inlet emerging into it. A wall separating the inside of the anode chamber from the outside thereof includes a main region having a first thermal conduction resistance between the outside and the inside of the anode chamber, and a region for promoting the condensation of water having a second thermal conduction resistance between the outside and the inside of the anode chamber strictly smaller than the first thermal conduction resistance so as to delimit a water condensation surface within the anode chamber. A channel for removing the condensed water connects the condensation area to the outside of the anode chamber.

The catalyst thin layer consists of electronically conductive catalyst nano-particles embedded in a polymeric matrix. The ratio number of catalyst atoms/total number of atoms in the catalyst layer is comprised between 40% and 90%, more preferably between 50% and 60%.
