“…For this purpose, after having proven that fuel cells can exhibit the electrical behavior of a regulated current source, as shown in Fig. 2, we carried out some preliminary tests reported in [2], with a 100 cm² single fuel cell feeding a small superconducting coil with an inductance value of 4 mH which parameters are given in Table I. These experimental tests revealed the potentialities of this technique.…”

“…current supply of superconducting coils. Indeed, we tested the association of a Melika Hinaje, Stéphane Raël, Kévin Berger, Rafael Linares, and Jean Lévêque are with the Group of Research in Electrical Engineering of Nancy, University of 100 cm² single fuel cell (FC) and a small superconducting coil, with an inductance value of 4 mH [2]. Once more, the experiment was convincing, this is the reason why we decided to extend the study to a large superconducting coil, with an inductance value of several henrys.…”

Abstract-In this paper, we propose to replace the usual dedicated electronic power supplies of superconducting coil, which are in most cases a huge volume and/or a low energy yield, by a 100 cm² single proton exchange membrane fuel cell (PEMFC). Indeed, fuel cells are electrochemical converters which can be considered as DC low voltage electrical source. Preliminary investigations led with a single proton exchange membrane fuel cell (PEMFC) could evidence the behavior as a DC current source, in which the current is directly controlled by the hydrogen flow rate. In a first step, we highlighted the feasibility by supplying a small superconducting coil, with an inductance value of 4 mH by means of a single PEMFC and proved that dedicated power source can be replaced by fuel cell. The second step is to feed a superconducting coil with higher inductance, 10 H, as presented in the present work.  Index Terms-power supply, proton exchange membrane fuel cell, superconducting coils.

“…In this paper, we propose an innovative application that takes great advantage of both PEMFC low voltage and current source behavior: the electrical supply for high-inductive superconducting coils. Hinaje et al [2] have already experimented, in GREEN laboratory, the use of a fuel cell for supplying current to a superconducting coil. However, the experiment was led on a low inductance superconducting coil , i.e.…”

“…As a matter of fact, for voltages below 100 mV, close to short circuit, the current delivered by the cell has been observed to correspond well to the flow rate of fed hydrogen according to Faraday's law – air oxygen was introduced in excess for these tests (Figure ). Besides the worked case of the above direct hybridization, applications for this specific operating regime can be power supply to superconducting coils – operated at very low voltages – as tested by .…”

Operation of PEM fuel cells at very low voltages can occur in the case of direct hybridization with supercapacitors, depending on their charge level: in such cases, the cell acts as reliable current sources that can be used with low voltage devices. In spite of the growing importance of this electrical mode aging phenomena for such conditions are still unknown. A single 100 cm2 cell was operated for more than 2,000 hours at short circuit. The current delivered by the cell provided with an MEA after suitable maturation, was shown to be approx. 98% of that corresponding to the injected hydrogen flow rate. The state‐of‐health of the cell was followed by impedance measurements and determination of the electrochemical surface area of the cathode and the fuel crossover. Significant, regular decay rate of the cell voltage after the low‐voltage run was observed to range from 30 to 100 µV h−1 depending on the current density. The features of the cell were little‐to‐moderately affected by the particular regime: 43% of ECSA was lost which affects only little the FC performance, and hydrogen crossover remains unchanged. Only the diffusion resistance was increased up to fourfold at high current density.
