Advent Technologies has unveiled its second-generation fuel cell membrane electrode assembly (MEA) technology, offering over double the power density of its legacy MEAs with significant potential for improved lifetime. The technology, developed under a US Department of Energy program, is designed for high-temperature PEM fuel cells and can utilize e-methanol, RNG, and hydrogen. Despite initial challenges from the first-generation technology, Advent MEA G2 has successfully increased power output and aims for further enhancements in the upcoming G3 version. The company emphasizes the advantage of liquid fuels like e-methanol over compressed hydrogen, simplifying the system and targeting deployment in off-grid, portable power, and marine sectors. Advent's chief strategy officer highlights the inefficiency of decarbonizing sectors with compressed hydrogen, advocating for the use of green hydrogen-based e-methanol instead. The company also stresses the low-phosphoric acid composition of the G2 MEAs, promising increased fuel cell system lifetime. With outstanding start-up/shut-down stability and reduced degradation rates compared to legacy MEAs, Advent predicts fuel cell systems can easily surpass 10,000 hours of operation even under extreme conditions. Additionally, the company has exceeded the DOE's heat rejection goal with their systems operating at 160-180oC. In terms of cost and efficiency, Advent aims to enable OEMs to manufacture fuel cell systems using e-fuels like e-methanol for a competitive CAPEX cost below $0.1/kWh. The company sees this as a cost-effective green solution that outperforms diesel gensets and combustion engines. Moreover, the article touches upon the challenges of storing and transporting hydrogen, highlighting the benefits of converting hydrogen to derivatives like ammonia or methanol for cost-effective storage and transportation.
