摘要:
A fuel cell system includes: a fuel cell (100); a secondary cell (200) that receives and stores surplus power by which output of the fuel cell (100) is greater than power demanded of the system if the output is so, and that compensates for shortfall by which the output of the fuel cell (100) is less than the power demanded of the system if the output is so; a voltage measurement portion (600) that measures voltage of the fuel cell (100); a current measurement portion (600) that measures current of the fuel cell (100); and a control portion (700) that performs a control such that the voltage of the fuel cell (100) does not exceed or equal a pre-set high-potential avoidance voltage. If a current-voltage characteristic of the fuel cell (100) declines by at least a pre-determined amount from an early-period level, the control portion (700) re-sets the high -potential avoidance voltage to a value that is smaller than an early-period set value.
摘要(中):
燃料电池系统包括:燃料电池(100); 二次电池(200),其接收并存储所述燃料电池(100)的输出大于所述系统所需功率的剩余电力,如果所述输出为正,则补偿所述燃料电池(100)的输出 100)如果输出是小于系统所需的功率; 测量燃料电池(100)的电压的电压测量部分(600); 测量燃料电池(100)的电流的电流测量部分(600); 以及执行控制使得燃料电池(100)的电压不超过或等于预定的高电位回避电压的控制部分(700)。 如果燃料电池(100)的电流 - 电压特性从早期电平下降至少预定量,则控制部分(700)将高电位避免电压重新设置为较小的值 而不是早期的设定值。
