Frequently Asked Questions

Q: Why does HYDRA-G 205kW use metallic bipolar plates instead of graphite plates?

A: Metallic bipolar plates can provide higher mechanical strength and enable compact high-power stack designs. For heavy-duty applications, they can help reduce system size and improve resistance to vibration and mechanical shock.

Q: Can HYDRA-G 205kW be used for MW-scale stationary power?

A: Yes. Multiple 205kW modules can be configured in parallel to build MW-scale power systems. The appropriate system configuration depends on load profile, hydrogen supply, redundancy requirements and site conditions.

Q: What's the benefit of the 330–750V voltage range?

A: The 330–750V DC range supports direct integration with many industrial DC buses, electric drivetrains and power conversion systems, depending on system architecture.

Q: How does the cost of hydrogen fuel cell power compare with diesel generation?

A: Project economics depend on hydrogen price, diesel price, utilization, maintenance, infrastructure and local energy costs. Hydrogen fuel cell systems can reduce mechanical maintenance and eliminate onsite combustion emissions, while the overall TCO should be evaluated based on the specific application and location.
