1. A heat-generating device comprising a fuel source, a fuel delivery connected to the fuel source, a catalyst dispersed over a porous substrate, the catalyst being in diffusive contact with an oxidizing gas, and a molecular selectively permeable membrane for selective molecular delivery of fuel by diffusion to the catalyst, wherein the fuel diffuses to the catalyst through the molecular selectively permeable membrane and the oxidizing gas diffuses to the catalyst through a different membrane or mechanical mechanism, further comprising an upper temperature limit setting on a thermal output caused by boiling the fuel.
