Labor Fuel Cell Stacks + customized Stack

Description:

We offer custom fuel cell stacks. Fuel cell stacks are multiple cells attached in series. The EFC50-CST custom stack is designed for the researcher to be able to select the operating characteristics of the fuel cell stack. The user specifies the number of cells, with a minimum of 7 MEAs (50 W) and a maximum of 30 MEAs (300 W). The stack design incorporates the same 50 cm² active area, identical to those of the 50 W stack. The total power output may vary based upon the environment (temperature, humidification, etc.) of the stack.
ElectroChems fuel cell stack is designed for ease of use and reliability. This unit will give you years of trouble free operation. The fuel cell stacks can operate without external humidification at pressures up to 3 atmospheres of H2 and O2. The EFC50-ST unit generates 50 W of power under normal operating conditions and can provide up to 100 W peak power. No gas recirculation is required, under normal operating conditions. ElectroChems stacks can be operated at utilization levels for pure H2 and O2 close to 98%. The recommended pressure for hydrogen and oxygen gases is 50 psig. Each plate includes a thermocouple well and a banana jack for accurate temperature and voltage measurement.
