The invention relates to a device (1) for checking the tightness of electrochemical cells (2), in particular with regard to H2 tightness. The device has a chamber (3) for accommodating and checking at least one electrochemical cell (2). For the purpose of the check, the chamber (3) is subjected to a vacuum. A unit (6) for gas supply is provided, which supplies an electrochemical cell (2) to be checked with compressed air, as a result of which the interior of the electrochemical cell (2) is pressurized. This is made possible particularly advantageously in that the pressure difference between the interior of the cell (2) having the excess pressure and the chamber (3) having the vacuum is particularly high and is additionally varied periodically. As a result, there is a particular incentive for a periodically varying gas transfer between the interior of the cell (2) and the chamber (3) under vacuum, which allows for the tightness to be checked particularly advantageously and meaningfully. The pressure sensor (7) allows for a periodic pressure increase in the chamber (3) to be detected and to be analyzed by means of the control unit (8), and for meaningful information regarding insufficient tightness to be obtained, without interference by non-periodic interfering effects, and made available to the user. The device according to the invention can detect very minor leaks, which for example lead to leakage rates in the range of 10-4 mbar per liter of the volume and per second, and a

Resumen de: EP4712174A1
A regenerative fuel cell has one half-cell which produces gas while charging and consumes the gas during discharge. The electrolyte liquid circulated through that half-cell contains a flexible long chain polymer or a viscoelastic surfactant. The half-cell is configured to compel the flow of electrolyte liquid to make repeated changes in direction and the flow rate is sufficient that elastic turbulence occurs. This dislodges bubbles of produced gas from the electrodes, maintaining more electrode surface available for reaction and enhancing efficiency. The other half-cell may also be in a state of elastic turbulence enhancing mass transport to and from its electrode surface
