选型参数
询价时需要明确哪些信息
该表用于询价前的品类级选型准备。具体数值需结合最终型号、规格书和项目工况确认。
| 技术参数 | 常见取值/选项 | 询价需提供 | 工程备注 |
|---|---|---|---|
| 燃料电池类型 | PEM fuel-cell stack, Air-cooled PEM module, Liquid-cooled PEM module, Integrated fuel-cell system | Stack/module/system scope, power class and integration boundary. | Clarify whether the quote is for a stack, module, balance-of-plant package or complete system. |
| 额定功率 | Portable watt-class systems, Kilowatt-class modules, Stationary or mobility system ratings | Rated power, peak power, duty cycle and required operating duration. | Differentiate stack power, net module output and complete system output. |
| 输出电压范围 | DC bus output, Battery-hybrid output, Custom converter output | Nominal voltage, allowable range, ripple limit and load profile. | Voltage range changes with stack current, converter architecture and hybrid battery design. |
| 额定/峰值电流 | Continuous current, Peak current, Transient current support | Continuous current, peak current duration and load transient profile. | Fuel cells are commonly paired with batteries or supercapacitors for fast transients. |
| 氢气纯度要求 | Fuel-cell grade hydrogen, ISO 14687-aligned specification, Project-specific purity limits | Hydrogen source, purity grade, impurity limits and supply standard. | Hydrogen purity affects catalyst life, performance decay and warranty conditions. |
| 供氢压力 | Low-pressure regulated supply, Cylinder supply with pressure regulation, System-specific inlet pressure | Available inlet pressure, regulator type, storage method and safety shutoff requirements. | Final pressure limits must follow the selected stack/module datasheet and local safety rules. |
| 氢气消耗量 | Consumption at rated load, Consumption by power output, Runtime per cylinder/tank | Target runtime, load profile and available hydrogen storage capacity. | Consumption should be evaluated against the real duty cycle, not only rated output. |
| 系统效率 | Stack efficiency, Net system efficiency, Efficiency at rated load | Required efficiency point, operating load range and auxiliary-power assumptions. | Net system efficiency includes pumps, fans, valves, controller and power conversion losses. |
| 冷却方式 | Air-cooled, Liquid-cooled, Integrated thermal-management loop | Ambient temperature, installation space, noise limit and continuous operating duration. | Air cooling is common at lower power; liquid cooling supports higher power and continuous duty. |
| 工作温度范围 | Indoor, Outdoor, Low-temperature start, High-temperature derating | Minimum/maximum ambient temperature, altitude and enclosure conditions. | Cold start and thermal derating should be specified separately from normal operation. |
| 启动时间 | Cold start, Warm start, Start after standby | Required start time, standby state and acceptable battery-assist behavior. | Start-up depends on purge strategy, temperature, hydration state and control logic. |
| 尺寸与重量 | Module envelope, System enclosure, Packaged shipping weight | Available installation envelope, mounting orientation, maximum weight and service access constraints. | For shipment planning, separate product net weight from gross weight and volume. |
| 防护等级 | IP54, IP55, IP65, IP67, IP68 | Target IP rating, indoor/outdoor use, wash-down exposure and dust environment. | IP ratings must be confirmed at complete product or enclosure level. |
| 安全与控制接口 | CAN, RS-485, Ethernet, Dry contact, Hydrogen leak detection, Emergency stop | Required communication protocol, alarms, interlocks, shutdown logic and integration controller. | Safety design must cover hydrogen detection, ventilation, pressure protection and electrical isolation. |
| 寿命与维护 | Stack operating hours, Maintenance interval, Performance degradation target | Annual operating hours, duty cycle, maintenance access and warranty expectation. | Lifetime depends on load cycling, hydrogen quality, temperature control and maintenance practices. |
