| 摘要 |
An electrochemical device comprises a primary magnet and a secondary magnet for applying forces to magnetic entities of an electrolyte. The primary magnet is arranged to induce a magnetic moment in the magnetic entities and the secondary magnet being arranged to create a magnetic field gradient in the vicinity of the magnetic entities to control the magnetic entities. The electrochemical device may be a fuel cell such as alkaline fuel cell or a proton exchange membrane fuel cell.
