Aspects include supplying a plurality of nickel-enriched braze powder particles to a cold spray system through a particle supply inlet. The nickel-enriched braze powder particles are accelerated through a transfer tube and out an exit in the transfer tube towards a substrate to produce a braze cold-sprayed substrate. A component surface is positioned proximate to the braze cold-sprayed substrate. The braze cold-sprayed substrate is heated to bond the braze cold-sprayed substrate to the component surface.

An Organic Rankine Cycle system is combined with a fuel cell system, with the working fluid of the Organic Rankine Cycle system being integrated directly into the cooling system for the fuel cell. The waste heat from the fuel cell is therefore applied directly to preheat and evaporate the working fluid in the Organic Rankine Cycle system to thereby provide improved efficiencies in the system.
