Abstract: Significant progress has been achieved in the development of nanomaterials for polymer electrolyte membrane fuel cells (PEMFC) and solid oxide cells (SOC). However, the limited scalability and multi-step processing of the conventional synthesis routes for the electrocatalysts, their supports and thin functional films in general (e.g., co-precipitation and solid-state synthesis) remain a great challenge for inexpensive production of these energy materials and cells. These drawbacks could be overcome by flame spray pyrolysis (FSP), a simple, rapid, scalable and single step fabrication technique. Here, a comprehensive review on flame-based synthesis and deposition techniques with a major focus on FSP for PEMFCs and SOCs is presented. Flame-made materials of practical importance including Pt, Pt alloys, metal-nitrogen-carbon catalysts, perovskites and catalyst support structures, and their performance are discussed along with challenges and opportunities to bridge the gap between materials research and cell development.
