The invention refers to a flow-promoting device (100; 100; 100) for performing a biological or chemical transformation, or physical or chemical trapping from, or release of agents to, a fluidic medium. The flow-promoting device (100; 100; 100) comprises a ferromagnetic material (5) and a retaining structure (1; 1; 1), the retaining structure having a compartment (9; 9) defined by a permeable material (11; 11). The retaining structure (1; 1; 1) comprises a top wall (3; 3) and a circumferential side wall (4; 4), wherein the top wall (3; 3) and the circumferential side wall (4; 4) is formed mainly by said permeable material (11; 11). The compartment (9; 9) of the retaining structure (1; 1; 1) is arranged to contain at least one fluid-permeable solid reaction member.

A hydrogen gas generating system that heats a liquid reactant such as water, then channeling the resultant heated reactant to a reaction chamber containing a solid hydride. The chemical reaction between the heated liquid reactant and solid hydride forming hydrogen gas. This hydrogen gas is then filtered and regulated before being stored in a buffer tank. Hydrogen gas from the buffer tank can then be supplied to a fuel cell to produce electricity as and when needed, such as when a battery goes below a predetermined level. The pressure of the buffer tank is measured and used to ascertain when the hydrogen gas generation should start and stop. A pressure and temperature of the reaction chamber is measured as a safety precaution, whereby the reaction will be stopped if the pressure and temperature exceeds predetermined values.
